Okay, another option would be to show the selector unconditionally for 
both VMs and CTs, but only ever enable it for the CTs.
That way one could also get rid of the `vmtype` check when disabling the 
selector below, and the window layout would remain the same for both 
types, making it less messy and error prone for future adaptions.

Opinions on that?
