I think that it would be nice if you could separate your friends on the server in active members and less active / inactive members. So, if you want to add a friend, but your friend list is full, you do now have a better overview of people who are less active and this might help you to make a better choice in which person you're going to remove from your friend list. It's not a crucial feature, but it would be pretty handy in my opinion!
