I thought this could be usefull, so that you can tell which contacts feel like chating or to seperate them from the contacts that don't feel like chatting / are busy or away.
The purpose isn't really to see which contacs have what status, but more to see which contacs are more likely to chat. Well i hope you get what I'm trying to say.
I would be very grateful to see this feature!
