Rotate cube with middle click on desktop

[LuNeder]

First of all, this addon is awesome, thanks for making it!!
The Cube was one of the things keeping me from migrating from XFCE+Compiz to KDE, so finding this made me super happy!

In Compiz, you can rotate the cube by clicking with the middle mouse button on the desktop. You hold it, move your mouse to rotate the cube and release the button when you're on the desired desktop to switch for it. Would it be possible to have this feature in here too?

(also it'd be cool if we could close the top and bottom of the cube, maybe with a picture in the top too)
