This may be my first review ever. I wasn't going to jump to a bad review just because the app changed, just because books in my collection are not as easy to sort if not impossible or because I can't seem to sort the shop by publisher or the fact that you removed all the books I currently had downloaded to my device. What makes it so you get 1 star is the fact that I logged on to see with the exception of 44 books out of 1000s, you've lost my read/unread data. Fix this and I'll reconsider.
