Or, how about better relay management, and the ability to turn on and off relays as if they’re communities. 

You have your invite only tree relay - maybe you don’t want to see everyone on nostr - just that one relay of people.

Maybe you don’t want to post to all the relays, just to that one?

You can turn them all on, turn on public ones, see everything- or turn them off and be selective. Maybe you just have a friends only relay….
