If a user realizes they screwed up and need to go back they close the library, copy the saved metadata.db over to the library to be restored, start Calibre back up, and it’s

This is a really bad idea and the master footprint of every disaster in a database system. Exactly this takes care of a not in sync and inconsistent library. There is already a (better and 100% save) build in solution. It is called Restore database (pls. see
