Adding new things is a bit of a hassle, too. The popup properties only works on the "my books" page from the list of ones you've already added - any other way to add a book to your library (like from browsing a list of titles where you can click "add to my library" or "my rating" in 1-5 stars) just adds it as "read", and you have to open a whole separate window just to add basic tags to it. It's kind of useless without tags. Also it's annoying that they call tags "shelves". You can't exactly put a book on more than one shelf!
