invisible bars?

Ok! I'm going to wait! i discovered this great program 2 weeks ago and i love it. It is exactly that what i was looking for a long time. The only thing i don't like is the ugliness of the bar when you put it out of the taskbar. That's the reason i asked for the feature. It woul be cool if Yuri can make something similar like the backgrounds of Y'z or Object Dock: a bar that is as wide as the summary of the icons, so that we could put f.e. two bars at the top or one on the centre of the right side. TruelaunchBar would become the one and only launcher if somedays there are something like tabs. :?: How can i let disappear the background of a freefloating bar completely to see just he icons?
