The Collections feature in the ConnSoft is excellent for book order in series- um -es. It lets you order the books as you like, rather than Alpha, and you can go to the collection to get to them rather than chasing them in the main book list. I'm presently keeping all my books in Collections just to avoid that main book list. I'm hoping that they'll allow a hierarchical file system, or at least collections on memory cards in a (not to distant) future firmware update.
