Idea:
Display a symbol or word by the name above your friend’s heads so you can easily see them in hubs/lobbies.
More information:
I’m sure there are many people on the server who have many friends and sometimes it can be hard finding your them in hubs or lobbies with all the other people around. I thought it would be a nice idea to have some sort of way to differentiate between people who are and aren’t your friends just by looking at them. A simple symbol by their name or display their name a different colour to show it would work well I think.
