"Lock in Rack" function...
Since many devices in the rack have rather small knobs and buttons it is easy to miss them with the mouse pointer and start draging the device by mistake. It should be nice to be able to lock the device in place to avoid this. Maybe a small lock symbol next to the fold/unfold symbol to lock or unlock the device?
