OK, so now I re-added the categories column. You can now sort by categories if you want to, weirdos.
Pinned posts look fine. BTW, you know you can un-pin a post once you’ve read it by clicking the thumbnail, right?
It really is annoying how Discourse changes how the forum functions in a minor update they strongly suggest everybody install and don’t add a simple switch to revert the UI change. Luckily other users posted the CSS to fix it.
@Thraeg: Anything staying the same spot can cause some burn-in on OLED, but you would need to leave the forum up for many hours on your phone without it ever going to sleep or leaving the forums, which is a very unusual use-case. I suggest not doing that.
Edit: I also added a theme selector to the “hamburger” button at the top right of your screen. Makes it much quicker to switch.
