We could add menu entries for un-/docking the widgets apart from the
buttoms in their title bars. Then there is no need to reset the complete
window layout. Sure, a better way would be to detect whether a widget is

detect this.


Thought it worth noting for posterity that on Windows 7+, you can just
Alt-Tab to switch to the non-visible window, then use the Windows Key + Left
