* Fixes position of the top arrow, and border width of both
* Merged top and transform properties
* .5px values are required to make arrow border appear the same with as overall popover border width
I did have a chance to try it out on a Windows machine with a non-high DPI display and there were no issues. And I just re-tested it with Firefox on macOS using the "Open in Low Resolution" option and it looked more or less ok (bearing in mind that it the whole app is then a blurry mess, and that using custom zoom levels causes the arrow to break slightly, but that was also the case on Firefox before this change)
This reverts commit 20780a1eee.
* SECURITY: re-adds accidentally reverted commit:
03d26cd6: ensure embed_url contains valid http(s) uri
* when the merge commit e62a85cf was reverted, git chose the 2660c2e2 parent to land on
instead of the 03d26cd6 parent (which contains security fixes)
* Do not show "Uncategorized" category in topics list.
* Use "BreadcrumbList" only if topic is in a category.
* Add tags list as keywords to the first post.
* Add "dateModified" even if it is the same with "datePublished".
* Show "crawler-linkback-list" only if there are links to be shown.
We now show an options gear icon next to the bookmark name.
When expanded we show the "delete bookmark when reminder sent" option. The value of this checkbox is saved in local storage for the user.
If this is ticked, when a reminder is sent for the bookmark the bookmark itself is deleted. This is so people can use the reminder functionality by itself.
Also remove the blue alert reminder section from the "Edit Bookmark" modal as it just added clutter, because the user can already see they had a reminder set:
Adds a default false boolean column `delete_when_reminder_sent` to bookmarks.
This will make a few minor improvements to the second factor user interface. Highlights include:
- Using the site's title to prefix the backup code filename. If non-ascii characters are detected, then prefix "discourse" instead.
- Add icons and change the text on some of the buttons for better clarity and consistency
- Add an education link to the security key modal
This adds a site setting (default off) to optionally show a user's local time and timezone in their user card. For example, I live in Brisbane, and if at 3:30PM my time I were to open a user who lives in California's card I would see 22:30 (PST).
Users can now edit the bookmark name and reminder time from their list of bookmarks.
We use "Custom" for the date and time in the modal because if the user set a reminder for "tomorrow" then edit the reminder "tomorrow", the definition of what "tomorrow" is has changed.
- Delete a positive tabindex from a reused component
- Copy :hover styles to :focus
- Replace an 'outline: 0' rule with a TODO for a custom :focus style
Discovered while fixing the no-positive-tabindex lint.
* Show the correct bookmark with clock icon when topic-level bookmark reminder time is set and show the time of the reminder in the title on hover.
* Add a new bookmark lib and reminder time formatting function to show time with today/tomorrow shorthand for readability. E.g. tomorrow at 8:00am instead of Apr 16 2020 at 8:00am. This only applies to today + tomorrow, future dates are still treated the same.
Color #ec7213: 3.0, Bold - AA Large Pass
Color #b06318: 4.50, Normal - AA Pass
Color #93704a: 4.51, Normal - AA Pass
Used the Chrome Inspector color picker curves to preserve the hue and make minimally invasive changes to the coloring.
If the feature is enabled, staff members can construct a URL and publish a
topic for others to browse without the regular Discourse chrome.
This is useful if you want to use Discourse like a CMS and publish
topics as articles, which can then be embedded into other systems.
* UX: removes color on categories if no style chosen
* Update app/assets/javascripts/discourse/templates/components/categories-only.hbs
* Update messages.hbs

Introduce the concept of "high priority notifications" which include PM and bookmark reminder notifications. Now bookmark reminder notifications act in the same way as PM notifications (float to top of recent list, show in the green bubble) and most instances of unread_private_messages in the UI have been replaced with unread_high_priority_notifications.
The user email digest is changed to just have a section about unread high priority notifications, the unread PM section has been removed.
A high_priority boolean column has been added to the Notification table and relevant indices added to account for it.
unread_private_messages has been kept on the User model purely for backwards compat, but now just returns unread_high_priority_notifications count so this may cause some inconsistencies in the UI.
Usage:
```
{{d-button icon="times" label="foo.bar" isLoading=true}}
```
Note that a button loading without an icon will shrink text size to prevent button to jump in size.
A button while loading is disabled.
* FIX: Perform crop using user-specified image sizes
It used to resize the images to max width and height first and then
perform the crop operation. This is wrong because it ignored the user
specified image sizes from the Markdown.
* DEV: Use real images in test
Based on issues identified in https://meta.discourse.org/t/improved-bookmarks-with-reminders/144542/20
* Implement the resolvedTimezone() function on the user model where we return the user's timezone if it has been set, or we guess it using moment and save it to the user using an update call if it has not yet been set. This covers the cases of users who do not log out/in often who will not get their timezone set via login. This also makes sure the guess + save is done in a non-obtrusive way not on every page -- only when it is needed.
* Before if a user's timezone was blank when they visited their profile page we were autofilling the dropdown with the guessed timezone from moment. However this was confusing as it would appear you have that timezone saved in the DB when you really didn't. Now we do not autofill the dropdown and added a button to automatically guess the current timezone to make everything more explicit.
* Improve the bookmark mobile on modal so it doesn't go all the way to the edge and the custom datetime input is easier to use
* Improve the rake task for syncing so it does not error for topics that no longer exist and batches 2000 inserts at a time, clearing the array each time
* Cosmetic fixes for the bookmark modal
* Do not show "later today" when the later time will be > 5pm
* When a custom reminder time is selected, store it in localStorage. The next time the modal is opened, if the last datetime is > now, then a new tile with "Last" will be shown that lets the user reselect that same time.
* Also add an explicit "No Reminder" option that is selected by default
* This PR changes the user activity bookmarks stream to show a new list of bookmarks based on the Bookmark record.
* If a bookmark has a name or reminder it will be shown as metadata above the topic title in the list
* The categories, tags, topic status, and assigned show for each bookmarked post based on the post topic
* Bookmarks can be deleted from the [...] menu in the list
* As well as this, the list of bookmarks from the quick access panel is now drawn from the Bookmarks table for a user:
* All of this new functionality is gated behind the enable_bookmarks_with_reminders site setting
The /bookmarks/ route now redirects directly to /user/:username/activity/bookmarks-with-reminders
* The structure of the Ember for the list of bookmarks is not ideal, this is an MVP PR so we can start testing this functionality internally. There is a little repeated code from topic.js.es6. There is an ongoing effort to start standardizing these lists that will be addressed in future PRs.
* This PR also fixes issues with feature detection for at_desktop bookmark reminders
PMs will now display an envelope icon next to the topic title in search results. This is especially useful when searching using `in:all`.
Co-authored-by: adam j hartz <hz@mit.edu>
Now if a group is visible but unmentionable, users can search for it
when composing by typing with `@`, but it will be rendered without the
grey background color.
It will also no longer pop up a JIT warning saying "You are about to
mention X people" because the group will not be mentioned.
Styling based on element-ids, it is impossible for themes/plugins to display multiple cards on a single page. Using classes is a more flexible approach. The element-ids are maintained for backwards compatibility with existing plugins/themes.
This new iteration of select-kit focuses on following best principales and disallowing mutations inside select-kit components. A best effort has been made to avoid breaking changes, however if you content was a flat array, eg: ["foo", "bar"] You will need to set valueProperty=null and nameProperty=null on the component.
Also almost every component should have an `onChange` handler now to decide what to do with the updated data. **select-kit will not mutate your data by itself anymore**
* DEV: Remove `.large-image` selector
This selector is no longer used in core and there's no reference to it in any of `all-the-plugins`.
* FIX: Adjust the broken image placeholder border
- Increase size of textarea when displaying generated codes
- Adjust maxlength of input field in JS UI
- Adjust maxlength of input field in no_ember UI
Follow-up to bff9880d63
* UI: Mass grant a badge from the admin ui
* Send the uploaded CSV and badge ID to the backend
* Read the CSV and grant badge in batches
* UX: Communicate the result to the user
* Don't award if badge is disabled
* Create a 'send_notification' method to remove duplicated code, slightly shrink badge image. Replace router transition with href.
* Dynamically discover current route
Our current topic admin menu is not always fully visible on a mobile
device, therefore some options are difficult to click.
To solve this issue, we can display the admin menu on the bottom of the
screen on mobile devices.
* FEATURE: allows plugins to add a global notice
Usage:
```
api.addGlobalNotice(id, text, options = {});
```
Options can be:
```
dismissable // Will display a button to hide the notice if true
html // will prepend html to the next if present
level // alert level, will usee css class of alert component
persistentDismiss // if true won't show notice again on reload
onDismiss // execute a custom action on dismiss
visibility // defines custom logic for notice visibility
```

Changelog is available here - https://github.com/necolas/normalize.css/blob/master/CHANGELOG.md
I decided that the easiest way to ensure it works would be checking different browsers. It looked good to me on Chrome, Firefox, Edge and IE 11. In addition, I checked 3 random themes.
- Using h4 instead of h3 for sub-categories.
- Show category description if it does not have subcategories.
- Implemented equivalent for mobile-view.
- Include description_excerpt in basic serializer. This is needed for
displaying second-level categories in category list.
Follow-up to 9253cb79e3.
The maximum level used to be one, which meant that a category could be
either a parent or a child. If it was a parent, the subcategories were
shown; if it was a child then the parent selector was shown.
With multiple levels of nesting, a category can be both a parent and a
child.
Adds a custom bookmark-clock icon to discourse-additional.svg for use with the new bookmarks with reminder functionality.
Also add some code to correctly refresh the post-stream icon for bookmark to show the clock after save.
Note: All of this functionality is hidden behind a hidden, default false, site setting called `enable_bookmarks_with_reminders`. Also, any feedback on Ember code would be greatly appreciated!
This is part 1 of the bookmark improvements. The next PR will address the backend logic to send reminder notifications for bookmarked posts to users. This PR adds the following functionality:
* We are adding a new `bookmarks` table and `Bookmark` model to make the bookmarks a first-class citizen and to allow attaching reminders to them.
* Posts now have a new button in their actions menu that has the icon of an actual book
* Clicking the button opens the new bookmark modal.
* Both name and the reminder type are optional.
* If you close the modal without doing anything, the bookmark is saved with no reminder.
* If you click the Cancel button, no bookmark is saved at all.
* All of the reminder type tiles are dynamic and the times they show will be based on your user timezone set in your profile (this should already be set for you).
* If for some reason a user does not have their timezone set they will not be able to set a reminder, but they will still be able to create a bookmark.
* A bookmark can be deleted by clicking on the book icon again which will be red if the post is bookmarked.
This PR does NOT do anything to migrate or change existing bookmarks in the form of `PostActions`, the two features live side-by-side here. Also this does nothing to the topic bookmarking.
This feature adds the ability to define synonyms for tags, and the ability to merge one tag into another while keeping it as a synonym. For example, tags named "js" and "java-script" can be synonyms of "javascript". When searching and creating topics using synonyms, they will be mapped to the base tag.
Along with this change is a new UI found on each tag's page (for example, `/tags/javascript`) where more information about the tag can be shown. It will list the synonyms, which categories it's restricted to (if any), and which tag groups it belongs to (if tag group names are public on the `/tags` page by enabling the "tags listed by group" setting). Staff users will be able to manage tags in this UI, merge tags, and add/remove synonyms.
* FEATURE: ability to add all active components to theme
* FIX: add a component to all themes takes only active ones
* FIX: move select components/themes to top
* FIX: improve defaultIsAvailable
* FIX: Add filter(Boolean) and remove btn class
* FEATURE: Ability to add components to all themes
This is the first and functional step from that topic https://dev.discourse.org/t/adding-a-theme-component-is-too-much-work/15398/16
The idea here is that when a new component is added, the user can easily assign it to all themes (parents).
To achieve that, I needed to change a site-setting component to accept `setDefaultValues` action and `setDefaultValuesLabel` translated label.
Also, I needed to add `allowAny` option to disable that for theme selector.
I also refactored backend to accept both parent and child ids with one method to avoid duplication (Renamed `add_child_theme!` to more general `add_relative_theme!`)
* FIX: Improvement after code review
* FIX: Improvement after code review2
* FIX: use mapBy and filterBy directly
* UX: adds hover effect on lightboxed images
This commits also adds two scss functions:
- is-light-color-scheme()
- is-dark-color-scheme()
This hover effect won't be added on dark color schemes, as images already standout nicely on dark backgrounds.
Co-Authored-By: David Taylor <david@taylorhq.com>
This commit attempts to fix two issues that affect quoted images.
The first issue is observed while loading. The 'position: absolute' CSS
property makes 'width' and 'height' behave differently. Instead of using
the known image size, this makes it use the computed width and height of
the image, which should be the right size, as shown to the user.
The second issue is caused by 'object-fit: cover' property which trimmed
the left and right sides of wide pictures to make them fit inside the
quote.
The group card and group members page were affecting each other and were
leaking members list and the query parameters which led to bad UX
experience and sub-optimal performance (client made more queries because
it was loading fewer members).
This commit refactors the group model to make it more consistent, remove
dead code, move error handling outside of model.
- Allow revoking keys without deleting them
- Auto-revoke keys after a period of no use (default 6 months)
- Allow multiple keys per user
- Allow attaching a description to each key, for easier auditing
- Log changes to keys in the staff action log
- Move all key management to one place, and improve the UI
In a category's settings, the Tags tab has two new fields to
specify the number of tags that must be added to a topic
from a tag group. When creating a new topic, an error will be
shown to the user if the requirement isn't met.
The 'automatically set primary group' checkbox looked like it was associated with the email membership. In fact, it applies to all members who join the group. This commit moves it next to the 'automatic trust level' setting, and puts them both under an 'Effects' heading
Bump onebox version, and add new styling
Commit, PR and Issue oneboxes are updated with a new design. Timestamps are now localized using local-dates (if installed).
This addresses the following issues:
- on iPad, with keyboard attached, the composer is no longer forced to full screen
- on iPad, with keyboard attached, the topic no longer scrolls when starting a
reply and then cancelling it
- switching between inputs and buttons (formatting, emojis, categories/tags, etc.) no longer
causes layout to bounce around
If the setting is turned on, then the user will receive information
about the subject: if it was deleted or requires some special access to
a group (only if the group is public). Otherwise, the user will receive
a generic #404 error message. For now, this change affects only the
topics and categories controller.
This commit also tries to refactor some of the code related to error
handling. To make error pages more consistent (design-wise), the actual
error page will be rendered server-side.
Bump onebox version to include new github rendering, and add relevant CSS
Avatars are reduced in size significantly, and icons are added to easily differentiate PRs and commits. The 'Issue:' prefix is removed from issue oneboxes, to make them consistent with commits and PRs.
* Fix broken security key 2FA on mobile login.hbs
* Show nicer error message when a security key already exists
* [COPY] Disable -> Delete for security key editing
* Standardize UI elements in 2FA prefs password confirmation
* Minor fixes to label location for resetPasswordProgress
Partially reverts 94ab48c by using Safari hacks on iPad again.
This brings parity in the composer UI between iPhones and iPads
Hides grippie and fullscreen toggle button when the keyboard is visible on iPads
Adds 2 factor authentication method via second factor security keys over [web authn](https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API).
Allows a user to authenticate a second factor on login, login-via-email, admin-login, and change password routes. Adds registration area within existing user second factor preferences to register multiple security keys. Supports both external (yubikey) and built-in (macOS/android fingerprint readers).
This applies to iPhones running iOS 13+.
Previous technique remains in place for iOS 12 and below.
Note that this does not apply to iPads on iOS 13 due to Apple no longer
identifying iPads in the user agent string.
* Extract QuickAccessPanel from UserNotifications.
* FEATURE: Quick access panels in user menu.
This feature adds quick access panels for bookmarks and personal
messages. It allows uses to browse recent items directly in the user
menu, without being redirected to the full pages.
* REFACTOR: Use QuickAccessItem for messages.
Reusing `DefaultNotificationItem` feels nice but it actually requires a
lot of extra work that is not needed for a quick access item.
Also, `DefaultNotificationItem` shows an incorrect tooptip ("unread
private message"), and it is not trivial to remove / override that.
* Use a plain JS object instead.
An Ember object was required when `DefaultNotificationItem` was used.
* Prefix instead suffix `_` for private helpers.
* Set to null instead of deleting object keys.
JavaScript engines can optimize object property access based on the
object’s shape. https://mathiasbynens.be/notes/shapes-ics
* Change trivial try/catch to one-liners.
* Return the promise in case needs to be waited on.
* Refactor showAll to a link with href
* Store `emptyStatePlaceholderItemText` in state.
* Store items in Session singleton instead.
We can drop `staleItems` (and `findStaleItems`) altogether. Because
`(old) items === staleItems` when switching back to a quick access
panel.
* Add `limit` parameter to the `user_actions` API.
* Explicitly import Session instead.
If you click a (?) icon beside the reviewable status a pop up will
appear with expanded informatio that explains how the reviewable got its
score, and how it compares to system thresholds.
* The read indicator now shows up when no member has read the last post of the topic (written by a non-member)
* The read indicator works on mobile and receives live updates from message bus
* The icon we display in the topic list was changed
* Added a title to the indicator to indicate its purpose when hovering over it
* Removes unused styles
This commit only removes unnecessary / duplicate styles. It does not cause any visual changes.
* adds class to `<h1>` tag in header topic info.
This is much better to target than `h1`
* removes unused styles
* header title margin adjustment
* minor header-title margin adjustments
* One more header-title margin adjustment
* Revert "Revert "FEATURE: Publish read state on group messages. (#7989) [Undo revert] (#8024)""
This reverts commit 36425eb9f0.
* Fix: Show who read only if the attribute is enabled
* PERF: Precalculate the last post readed by a group member
* Use book-reader icon instear of far-eye
* FIX: update topic groups correctly
* DEV: Tidy up read indicator update on write
* Reenable: "FEATURE: Publish read state on group messages. (#7989)"
This reverts commit 67f5cc1ce8.
* FIX: Read indicator only appears when the group setting is enabled
* Enable or disable read state based on group attribute
* When read state needs to be published, the minimum unread count is calculated in the topic query. This way, we can know if someone reads the last post
* The option can be enabled/disabled from the UI
* The read indicator will live-updated using message bus
* Show read indicator on every post
* The read indicator now shows read count and can be expanded to see user avatars
* Read count gets updated everytime someone reads a message
* Simplify topic-list read indicator logic
* Unsubscribe from message bus on willDestroyElement, removed unnecesarry values from post-menu, and added a comment to explain where does minimum_unread_count comes from
This adds support for a `<d-topics-list>` tag you can embed in your site
that will be rendered as a list of discourse topics. Any attributes on
the tag will be passed as filters. For example:
`<d-topics-list discourse-url="URL" category="1234">` will filter to category 1234.
To use this feature, enable the `embed topics list` site setting. Then
on the site you want to embed, include the following javascript:
`<script
src="http://URL/javascripts/embed-topics.js"></script>`
Where `URL` is your discourse forum's URL.
Then include the `<d-topics-list discourse-url="URL">` tag in your HTML document and it will
be replaced with the list of topics.
Theme developers can now add any of the transformed color variables to their color scheme in about.json. For example
```
"color_schemes": {
"Light": {
"primary": "333333",
"secondary": "ffffff",
"primary-low": "ff0000"
}
},
```
would override the primary-low variable when compiling SCSS for the color scheme. The primary-low variable will also be visible in administrator color palette UI.
This feature adds the ability to customize the HTML part of all emails using a custom HTML template and optionally some CSS to style it. The CSS will be parsed and converted into inline styles because CSS is poorly supported by email clients. When writing the custom HTML and CSS, be aware of what email clients support. Keep customizations very simple.
Customizations can be added and edited in Admin > Customize > Email Style.
Since the summary email is already heavily styled, there is a setting to disable custom styles for summary emails called "apply custom styles to digest" found in Admin > Settings > Email.
As part of this work, RTL locales are now rendered correctly for all emails.
* UX: Show a warning when admin clicks save without adding group when changing category permissions
* Use div rather than pseudo element
* Don't pass controller to component
* Use observer instead of a delay
* Refactor
* Rename to validator
* validator is much better than saveValidator
This commit contains 3 features:
- FEATURE: Allow downloading watched words
This introduces a button that allows admins to download watched words per action in a `.txt` file.
- FEATURE: Allow clearing watched words in bulk
This adds a "Clear All" button that clears all deleted words per action (e.g. block, flag etc.)
- FEATURE: List all blocked words contained in the post when it's blocked
When a post is rejected because it contains one or more blocked words, the error message now lists all the blocked words contained in the post.
-------
This also changes the format of the file for importing watched words from `.csv` to `.txt` so it becomes inconsistent with the extension of the file when watched words are exported.
If a post arrives via email but must be reviewed, we now show an
icon that can be clicked to view the raw contents of the email.
This is useful if Discourse's email parser is acting odd and the user
reviewing the post wants to know what the original contents were before
approving/rejecting the post.
* FEATURE: Allow choice of category when making a PM public
Previously it would default to uncategorized, which was not ideal on
some forums. This gives the staff member more choice about what they'd
like to do.
* Make the optional category more explicit
* Joffrey's feedback
* FEATURE: Allow customization of robots.txt
This allows admins to customize/override the content of the robots.txt
file at /admin/customize/robots. That page is not linked to anywhere in
the UI -- admins have to manually type the URL to access that page.
* use Ember.computed.not
* Jeff feedback
* Feedback
* Remove unused import
This allows you to temporarily disable components without having to remove them from a theme.
This feature is very handy when doing quick fix engineering.
The global setting disable_search_queue_threshold
(DISCOURSE_DISABLE_SEARCH_QUEUE_THRESHOLD) which default to 1 second was
added.
This protection ensures that when the application is unable to keep up with
requests it will simply turn off search till it is not backed up.
To disable this protection set this to 0.
Adds a second factor landing page that centralizes a user's second factor configuration.
This contains both TOTP and Backup, and also allows multiple TOTP tokens to be registered and organized by a name. Access to this page is authenticated via password, and cached for 30 minutes via a secure session.
* SECURITY: Add confirmation screen when logging in via email link
* SECURITY: Add confirmation screen when logging in via user-api OTP
* FIX: Correct translation key in session controller specs
* FIX: Use .email-login class for page
This commit attempts to improve the experience by:
- showing time input as disabled on any platform if date hasn't been set
- showing a placeholder --:-- to emphasize the expected format
We now show if a queued or flagged post is a reply to another when in
the review queue. It's especially helpful for queued posts where
normally they are linked to the topic where they are created, and you
have no context about the reply.
Note that this will only apply to new queued posts going forward.
Previously queued posts will not show the "in reply to"
* Cleaning up crawler styles, improving some schema.org markup
* Cleaning up crawler styles, improving some schema.org markup
* additional styling
* add space for pagination
* FEATURE: detect theme errors and catch them
* Bump COMPILER_VERSION
* Feedback
* Override eslint no console for one line
* Can't use our ajax method
* remove emoji from translation file
This is a feature that used to be present in discourse-assign but is
much easier to implement in core. It also allows a topic to be assigned
without it claiming for review and vice versa and allows it to work with
category group reviewers.
This change shows a notification number besides the flag icon in the
post menu if there is reviewable content associated with the post.
Additionally, if there is pending stuff to review, the icon has a red
background.
We have also removed the list of links below a post with the flag
status. A reviewer is meant to click the number beside the flag icon to
view the flags. As a consequence of losing those links, we've removed
the ability to undo or ignore flags below a post.
* Fix header size to fit the viewport
Setting the header to border-box means that the padding is factored in when calculating its width. If this is not done, the header width would be 100% of the viewport width + any padding when set on it. That causes some parts of the header to be rendered off-screen and causes horizontal scrolling.
* prevent code in posts from causing horizontal overflow
We are currently not wrapping code in posts in the crawler view. This affects both unformatted code and inline code blocks. This commit forces such code to wrap in order to prevent horizontal overflow which the Google bot complains about since it causes some content to be rendered outside of the viewport for the mobile crawler.
This change automatically resizes icons for various purposes. Admins can now upload `logo` and `logo_small`, and everything else will be auto-generated. Specific icons can still be uploaded separately if required.
## Core
- Adds an SiteIconManager module which manages automatic resizing and fallback
- Icons are looked up in the OptimizedImage table at runtime, and then cached in Redis. If the resized version is missing for some reason, then most icons will fall back to the original files. Some icons (e.g. PWA Manifest) will return `nil` (because an incorrectly sized icon is worse than a missing icon).
- `SiteSetting.site_large_icon_url` will return the optimized version, including any fallback. `SiteSetting.large_icon` continues to return the upload object. This means that (almost) no changes are required in core/plugins to support this new system.
- Icons are resized whenever a relevant site setting is changed, and during post-deploy migrations
## Wizard
- Allows `requiresRefresh` wizard steps to reload data via AJAX instead of a full page reload
- Add placeholders to the **icons** step of the wizard, which automatically update from the "Square Logo"
- Various copy updates to support the changes
- Remove the "upload-time" resizing for `large_icon`. This is no longer required.
## Site Settings UX
- Move logo/icon settings under a new "Branding" tab
- Various copy changes to support the changes
- Adds placeholder support to the `image-uploader` component
- Automatically reloads site settings after saving. This allows setting placeholders to change based on changes to other settings
- Upload site settings will be assigned a placeholder if SiteIconManager `responds_to?` an icon of the same name
## Dashboard Warnings
- Remove PWA icon and PWA title warnings. Both are now handled automatically.
## Bonus
- Updated the sketch logos to use @awesomerobot's new high-res designs
- moves footer nav to the header on iPads
- disables scrolling events for iPads
- removes footer nav entirely on Chrome PWAs
- toggles DiscourseHub iOS app status bar styling (dark/light) when opening/closing lightboxes and modals
