Good barcode scanner, attractive interface.
Really needs more customization options, though - a books page has a huge number of data fields, most of which the average user wouldnt care about. Its good that theyre available, but the user should be able to select which ones they see and in which order.
Also, having the Personal information at the very bottom instead of just under the basic Title - Author - Publisher is an odd choice. Most people are more concerned with the collections their book is in and the star rating theyve given it than the name of the editor. (And even within Personal Information, why is the price info at the top?)
Finally, the collections feature needs to be revamped. They stay in the order theyre created in (instead of alphabetizing), cannot be renamed, and are inconvenient to access for viewing - you can to navigate several levels of the filtering tree to view one, and then go back and do it all over again to switch to another.
There should be a straightforward "collections" tab that allows to quickly view, edit, and add new empty ones. Also it would be nice to set the sort method for each collection independently - for some listed I might sort by Author, others Title, Rating, or Pagecount.
