I suggest a friend or buddy system. Let me explain. So I would like a way either by command or any way to add people as a friends. Now when I add people as friends by typing a command /friends or something similar I get to know which of them are online and which are offline and also I would like in the tab menu ( player list ) that my friends are highlighted in a special color like purple, red or some color. That is my suggestion. It is a little thing but it can be neat.
