good idea, needs features...

This app is a great (though not remotely unique) idea. It has a clean, simple interface. Unfortunately, it is lacking many features that are necessary to make it useful for most users. For a paid app, I would expect regular addition of such features. First, there ought to be a way to import purchases from online store (like amazon) accounts all at once. The only way to add ebooks that you own is to search individually online. Further, you should be able to sort books in a wide variety of ways (author last name, title, topic, genre)- which means you should be able to add tags or keywords to entries. It would also be good to be able to somehow sync your goodreads and/or librarything and/or shelfari accounts. it should be able to allow you to note how many copies of a particular book are in your library, and what formats they are in. For example, there are a few books which I own in hard cover, multiple paperback copies, mobi, ePub, and PDF...
There are a lot more features that could be useful, but I think that these features are absolutely essential for the pro app.
