See all communities on another instance? - eviltoast

Is there any way to see a list of communities either on the instance you’re subscribed to, or better still a remote instance? I can go to Local and New posts to see what’s been posted, but that’s really about it. Even if there’s a way to see communities of an instance you have an account on, I wouldn’t want to sign up for multiple instances just to get a list on each one, then flip back to my main account to subscribe to them.
