chaley - thanks for chiming in, I'd be in favour of disabling Rename and Delete when a VL is in play.
An alternative would be to make the confirm message very explicit as I suggested, and maybe remove the checkbox to hide the message (or make it a 'for this session only' hide).
When a VL is active one of the things one can't do is to drag a book to a Tag that's not already assigned to another book in the same VL. So would it be possible to provide a toggle to decouple/couple the the Categories sidebar (Tag browser) from Virtual Libraries. I'm thinking it would be in the white space context menu with Show all categories and Change sub-cat scheme.
Also, would it be possible to have a preference that would decouple the Manage... function from Virtual Libraries.
I think I know the answers, but... Newton, apples and all that
