* Add a gap between thumbnails on mobile.
* Adjust CSS for scores and vote buttons.
* Include "Private favorites" as an incentive on the user upgrade page.
* Fix vote buttons not being visible beneath thumbnails on mobile.
* Fix the "Show scores" link not preserving the current page number.
* Fix vote buttons being unintentionally enabled for all thumbnails by default.
* Fix banned and restricted users being able to favorite posts by
tagging them with `fav:self`.
* Fix search engines being able to crawl /posts?view=score pages.
* Fix broken tests.
Add upvote and downvote buttons beneath thumbnails on the post index page.
This is disabled by default. To enable it, click the "..." menu in the top
right of the page, then click "Show scores".
This is currently a per-search setting, not an account setting. If you
enable it in one tab, it won't be enabled in other tabs.
Fix various elements to use standard font sizes instead of ad-hoc sizes.
Noticeable changes:
* Tags in autocomplete are slightly smaller.
* The favorite heart icon on posts is slightly smaller.
* Pool titles on thumbnails in the pool gallery page are slightly bigger.
* The page footer is slightly smaller.
* Timestamps on comments and forum posts are very slightly smaller.
* "Pending"/"approved"/"rejected" labels on forum posts are very slightly smaller.
Show the length of videos and animated posts in the thumbnail. The
length is shown the top left corner in MM:SS format. This replaces the
play button icon.
Show a speaker icon instead of a music note icon for posts with sound.
Doing this requires doing `.includes(:media_asset)` in a bunch of
places to avoid N+1 queries when we access the post's duration.
Instead of changing the background color of the entire page when you
change modes in the post mode menu (which was ugly, and not obvious what
the colors meant), show a notice and make it so that hovering a post
gives it a blue outline. This indicates that clicking the post will do
something different.
* On the post show page, in the parent/child box, change it so that
currently selected post is more visible. Use a light blue outline
around the current post instead of a dark semi-transparent border.
* Fix it so that there's less empty space around thumbnails in the
parent/child box.
Refactor the post preview html to use the ViewComponent framework. This
lets us encapsulate all the HTML, CSS, and helper methods for a UI
component in a single place.
