No. I haven't seen the GUI, since I use it every damn day. -_-
The options are actually pretty good. If there was some way to combine :
MSN's ability to change names
MSN's games
MSN' GUI
AIM's Invisible Mode feature, yet you can still send people messages without having to become visible again
AIM's Away Messages feature
One of AIM's add on applications, DeadAIM for being able to log into multiple accounts and also log all convos, including pictures.
YIM's Offline Messaging feature (aka, one user is offline, you can leave him a message that he will see when he next get's online)
