I don't know if this topic has been done before or if it counts as a suggestion but I would think that minecraft could benefit from a list that you can open in the pause menu or on any menu in minecraft so that way people can add friends and join them on server together. With this it could make playing on servers a lot more simple than chatting with them on skype or on a irc or forum. This is just a simple suggestion that could befit people with friends that play. Adding would be as simple as searching a name and sending a friend request.
Please no bad criticism I am bad at writing things.
