Lemmy as a whole is a pain for that. It's one thing when in the feed I read/vote/comment something and I want that hidden from the feed to remove clutter. But when I specifically search for it or browse a community I don't want those posts hidden. Obviously.
Yeah, it’s easy to hide but difficult to show hidden in most apps. That’s why I appreciate Avelon’s “Show Read Posts” option under the 3 dots on the main feed.
