It would be nice to have a "transparent" window option, like "send to" workspace.
Either with diffrent transparency values, or just as one option.
In combination with "always on top" it would make information windows possible which are always visible, but don't go in the way. Like a clock or "distcc-gnome"
To make it really useful without focus clicks shouldn't go to it, but to the windows behind it, so it just don't get in the way.
To regain focus for such a window, and do anything with it, you could click in the windows list.
It would also be nice if the xfce window bar disapears on it without the focus, it wouldn't add much information.
This would make compositor useful apart from eyecandy, and I could really use it in day to day work.
