I can hook you up with something, dude. But it would just be a drag and drop bar, can be autohidden off screen, but it won't automatically match the blind taskbar that you use it with.
I can, however, add instructions on how to make it match with a little work on your part.
Copying the taskbar image out of the current blind, and replacing the bar background with it could be done on a blind by blind basis.
Maybe, if I ask, sviz might be able to come up with a script that would allow you to drag and drop a graphic onto it and have it take on the characteristics of said graphic.
