It does that already. Shows you "Follow Back" if they already do. Briefly unfollow to see if they follow ππ«΅

Yeah, but unfollow follow seems like spam...
Hehe the amethyst users don't get notified when you follow (dunno about other clients). So might be spam only for relays depending. But I head you, you wanted lil text that says "follows you" somewhere. I'm down
Also a follow notification would be nice, but I think that's not trivial.
And while we're here, another feature would be to show who liked a note. That's in the notification for your own posts, but it's interesting to see for other people's posts too.
