Win7 Show Desktop [Plasma 6]

A fork of the default plasmoid but removes the icon and looks like a flat thin button. Can be configured to minimize all windows instead of "peaking" at the desktop, or to run a command. Scrolling over the button changes the volume, switch desktop, or any other command.
