When reading posts sorted by date, I often have the timeline import a whole bunch of old posts from one community at the top. This is annoying since I basically have to reload the page, otherwise all relevant content is gone.
The new sort is pretty important, since Lemmy doesn’t have a lot of posts anyways.
I dont think I found anything useful back then. So you can fill in the issue template and post it here, then someone can copy it to Github.
