For now, I'm going to stick to creating tags based on tags which is genre for most books and fandom for fanfiction.
I changed the import script to delete empty collections.
By the way, to delete an empty collection on the Kindle, touch the collection name until a menu pops up asking if you want to add/remove items or rename/delete the collection.
