Thanks for the suggestion, I downloaded Job Spy from the plugins list in calibre, it doesn't do what I need here, but it has some useful features (the metadata reference book and change modified date to mention a couple). I think I'll be using this to some extent, especially once my out-of-control library is in better shape
All OS's seem to discriminate against people who like dark themes. My inner goth is screaming for attention, lol
