Looks like your truing to turn it unto another MSN messenger. The "Add Icons" feature has been discussed many times. Like here and here and here. That was only the first page of search results.

Been so busy searching I must have forgotten what else you had suggested. Oh wait, there was just a modified screenshot with no list of suggestions attached, I was never too good at those "whats different" comparison puzzles, or the "mini spy" in the Sunday paper.
