When i get on the server it says that i have a friend request sometimes but if someone friends me while i'm in the server it doesn't show up until i get on the server again. i think that you should be able to accept or deny friend requests while on the server so you don't have to go on again for it to show up. when i do /friends list it shows my friends in a red name but i think, if they are online then it should be a green name and if i want to join them then i should be able to click on that name and teleport to them. almost like mineplex you can do /friend and it shows a invintory if they are online you can click on their head and you are teleported to them. if they arn't online then it should show when they were last on.
