This isn't really a feature suggestion, but rather a quality of life improvement.
Lately I've been getting a lot of messages saying "All posts hidden on page ### - RETRY" due to having to have so many filters on Lemmy to hide whole communities.
Just this morning I had to hit retry about 6-7 times in a row because there were 6-7 pages on posts completely filtered out..
Had the same issue on sync for reddit but it wasn't as noticeable since filters weren't required as much. On Lemmy it's a staple and kind of annoying once you have a fair bit of communities filtered out.
