Automatic Book Shelf / Subject Area#325

Would love it if there was an option to “automatically” catalogue your books into subject areas (ie. shelves)

+1 if we could access all kinds of metadata in those automatic shelves, like reviews, whether I have seen the book (marked want-to-read, put on a shelf, added a snippet or anything else), and odd genres like the ones Netflix generates such as “campy scifi” and other categories. I guess I’m voting for a rich advanced search that could be saved and shared.
