I think it would be nice to have a plugin where you can be notified by sound or popup, when a user on your contact list begins to type you a message.
I know that when you are in a chat, it shows in text that the users is typing, but I would like to get a heads up when someone is beginning to type to me.
Very handy for business related chatting.
It would be sneaky too, to find out who changes there mind and never sends you that message.
