You know something that has kinda been grinding my gears about Lemmy so far? I can find new communities on other communities federated with mine. However I cannot click on any of the links they leave for the other communities and have to search for them manually through my search bar. If I could just click on a link to another community and have the app retrieve it through my instance, that would be really cool and would add a lot to the user experience of the fediverse.
Liftoff kind of has this feature already. When you’re in a different community and try to subscribe to it it asks you what account you want to use and are directed to what your instance has from that community. Then you can browse away and don’t have to actually subscribe.
