Yuck. Nothing personal against Khaled. It just doesn't look good if you have lots of them going up at the same time.
Lets suppose that someone needs lots of these sorts of windows for server notices (opers), services messages (custom nickserv/chanserv stuff), or even just script messages - having a window pop up with that @ box thing in both the main taskbar and the window itself doesn't look as good as it COULD look.
I really didn't have many original ideas of my own on this matter. I'm sure other people would though.
