Because of the currently small size of Lemmy, I tend to see the same posts over and again. Is it possible to add mark as read button so that I don't have to click into and out of posts that I don't want to see anymore?
There's a "hide read" feature. With smaller communities this tends to be a more common issue. If you're seeing it on your front page, then I'd recommend changing from Active to Hot sort for newer content.
