"hide all child comments" was a much beloved feature on BaconReader, at least for me.
I also preferred the card view of content, and that all read content would get hidden.
But this is something new, so I'm trying not to compare them directly - I don't really want Lemmy to just be new Reddit, but something new.
I'm using Jerboa, and it still got me.
Still figuring out what view mode works best, it's going to take me a long time to unlearn over a decade of BaconReader..!
