Discord Invite List

I think it is kinda annoying when you want to keep an invite for your friends server but dont really want to stay in it. I think it would be cool to be able instead of when you invite someone via the right click function it goes to a "Server Invites" modal or something and there is a list of servers you are invited too. And depending on like what other server names your in discord would also automatically recommend you to some servers. Also on this I think it would be cool to only allow certain users to join a discord server like a whitelist on the server. I think both of these would be some nice suggestions.
