Is there a switch to enable a feature known in Aero as 'transparent glass' in KDE? Currently with the smooth-tasks widget installed, you almost get this effect, except it's a bit different where the window displayed after taskbar hover can be difficult to read when all other windows over that window are also displayed with some transparency. In Windows Aero, the hovered window is completely displayed as if the user selected that window to pop it to the top of the stack.

Thanks,
Chris
