I am very happy with the 1.5 update. I never had an issue with the page turns before, but it's so much faster, that I now wonder how I managed before.
I love the Shelves feature but hope to see it improved in the future, such as syncing shelves to my B&N account and improved functionality. I don't see why B&N doesn't just remove the distinction between store-bought content and "My Documents" and just have it all appear to the reader as one library? I'd love to see that.
One weird issue I ran into is if I created a shelf while in the B&N Library, it would be grayed out if I switched to My Documents and entered the mode to place / remove books from shelves; however, this did not happen when performed the other way around. Has anyone else seen this?
