friend adding

Hey, I just played Battle Arena and met this cool player. I wanted to add him in my friendlist, but he has multiple Spaces in his Name like ´A BC´, and because of the Spaces I couldn´t add him. I tried to use "" but it didn´t work. How can I add him?

I have a problem. When I type "/f list" there is (2/ -1) friends. When I try to add someone there types "that you have reached limit of friends" . I deleted Cubecraft server and added it again, but it doesn't work, so I deleted Minecraft and installed it again, but it still doesn't work. Please...

It'd be cool if you could shift right click people in the lobbies to open a GUI like the picture in the attached files, to friend, party or message them I'd like to see this be added let me know that you think -Edgeless

I have seen this on a few other servers where when you go to your lobby selector you can see what lobby your friends are in. It would be very helpful and save a lot of time chatting between your friends to pick the same lobby.
