I'll add another feature request that I forgot: instance browsing. Being able to see a list of communities within a remote instance would be nice (preferably sorted by subscribers like in the web UI). Being able to see the Local feed from a selected remote instance would also be useful. I think both those features could help with community discovery.

EDIT: disregard most of this, I was blind to the instances button. It would still be nice to see the communities-list on an instance sorted by size.
