This was a feature that I fell in love with on Boost. I like to sort by top day and do short quick bursts of scrolling through the feed, so it helped a lot.
I’m not even sure if it’s possible on lemmy, or if anyone else feels they’d get use from it as well.
Workaround on Jerboa (maybe also other apps, haven’t checked) - turn on “hide read posts” and simply upvote/downvote as you scroll. Upvoting/downvoting marks posts as read in Jerboa even if you haven’t clicked in, so it’s pretty effective.
It’s a nice workaround for sure, but the only thing I don’t like is that it auto-updates. If I click on a post and then go back to the list, the post is gone. I wish it only hid the post until I manually refreshed the page.
