Why this change?
We are currently not fully satisfied with the current way to edit the
categories and tags that appears in the sidebar where the user is
redirected to the tracking preferences tab in the user's profile causing
the user to lose context of the current page. In addition, the dropdown
to select categories or tags limits the amount of information we can
display.
Since editing or adding a custom categories section is already using a
modal, we have decided to switch editing the categories and tags that
appear in the sidebar to use a modal as well.
This commit removes the `new_edit_sidebar_categories_tags_interface_groups` site setting and
make the modals the default for all users.
This PR splits up the preference that controls the count vs dot and destination of sidebar links, which is really hard to understand, into 2 simpler checkboxes:
The new preferences/checkboxes are off by default, but there are database migrations to switch the old preference to the new ones so that existing users don't have to update their preferences to keep their preferred behavior of sidebar links when this changed is rolled out.
Internal topic: t/103529.
Communities can use sidebar or header dropdown, therefore navigation menu is a better name settings in 2 places:
- Old user sidebar preferences;
- Site setting about default tags and categories.
