Simple idea, I think. Nothing flashy. Someone sends you a tell: a SMALL... I repeat SMALL icon appears on screen that flashes non obnoxiously or something and possibly displays a toon name and clicking on it opens a pop-out window for IM'ing the person who sent you the tell.
I understand there is already a popout window and a ding and a blue icon, but they're just so subtle it's very easy to miss. Just a thought.
