Now we have an icon that tells you when a friend is online (yellow and happy) or not (red and sad). Sun Tzu said a long time ago "keep yor friends close, but your enemies closer". I believe that I am not the only one who keeps track of "friends" this way. It would be great if we could choose the color of the icon when rthe "friend" is online. Red, yellow and green could just work fine and we could know how close we are to our friends.
