@mehetabelo:
I hadn't given any thought to title/author swapping but it is an interesting issue you raise. I guess the question is whether that is a function of a duplicate checking plugin or whether some other plugin should try to detect this (like Quality Check).
Certainly using a "staging database" towards a clean database is an approach I've heard a number of people taking, your approach sounds very diligent
Re the keyboard shortcuts - I probably forgot to wire them in
. I will take a look.
