Perhaps I've misunderstood the purpose of the check boxes and selectors and the way they interact. But, it doesn't seem right to have the check boxes enabled when there is nothing in the corresponding selectors, viz:
Perhaps the check boxes should be after the selectors and only enabled if there is something in the corresponding selector.
The check boxes and selectors have the same tooltip e.g.
"Switch to the selected Virtual Library when the View is activated.". I suggest the check box tooltips have something like
"Enable/disable switching to the selected Virtual Library when this View is selected" -- If two widgets have the same tooltip it begs the question, why are there two widgets
