It would be nice to add an option to exempt books based on author, title-part or tag
and authors based on tags or part of name.
Then it would be possible to exempt:
books of calibre (news)
books with special tag (other version, second edition)
books with special part in name [other version] [.. edition] <- tricky, what would you do in case of 4th edition, 4th edition and 5th edition. Ignore all or show the 2 4th edition versions?
Authors with special label (my fav author, English Author 1950, Dutch Author 1968)
Authors with special parts (Jr.)
