In this thread over in breezy dev forum some users were talking about gksu's latest version 'greying out' the background when a user launches something that needs gksu. I have this on my sid box and it's kinda nice. I guess it basically emphasized the point that the user could not launch anything else when a gksu gui prompt was present.
Not a big thing on my wishlist for backports so if it gives you any headaches don't worry about it.
