I've tried Jerboa and Connect. They are ok, but there are features I'd like.
Biggest feature is account backup and transfer. If I switch Lemmy instances, I don't want to have to sub and block all the same channels and people. Heck, maybe keep two accounts always in sync, just in case my initial instance goes down.
Instance blocking. Basically individual defederation by hiding posts and users in the client.
Blocking all subs of a name regardless of instance. If I don't want to see a sub about Foo on one instance, I probably don't want it anywhere.
Keyword blocking. There are public figures I am tired of. Don't need to see any post about them. (Connect actually has this, although I haven't tested it yet).
Really easy channel blocking. Just swipe and it's blocked.
I just hope it works, all of the apps I've used on Android have been so fucking buggy lol. Idk if it's Lemmy's backend or just poorly developed apps but man lemmy is forcing me to work hard to like it haha.
I don't think it's much to ask for an application to do the basic things it promises to do. Also Lemmy has been in development for four years so not really "new."
