@drMerry - thx for adding suggestions.

I've worked very hard to avoid adding custom columns as they add a whole layer of complexity and issues that is best avoided if possible. At the moment the groups are sorted in an "alphabetical" way. I would rather just offer a suboption on the find duplicates options gui to let you sort them by # duplicates (and alphabetically within that). The question is - do others find that of interest or is it niche?

In terms of the merge menu options, it should already automatically remove a merged group out of the view when you go "next group" - is that not happening? So the only thing from your list that I see missing is "Change selected group to selected book". The problem with that is a book can be in multiple groups, so how would it know which group you meant?

For instance if I have books 1,2,3 and exemption (2,3) then I will have group A of (1,2) and group B of (1,3). So if I selected book 1, how would I know you wanted to see Group A or Group B?
