I don't actually want to hide all the posts I have read, since a lot of them are things I want to go back to. What I really want to hide are posts that I am not interested in. Is there an app that will let me select which posts to hide? Or is that feature under development? As Lemmy grows, it's becoming a huge issue that I can't prune my feed without unsubscribing from whole communities.
Yes, you have to read the OP to mark it as read. After read, with new comments, post will remain as read.
There is no way for that at the moment, but I think this is great idea!
