I've just upgraded from a Kindle 3 (Kindle Keyboard) to the new Paperwhite, and I'm confused about how collections now work (although this may have changed in Touch, not sure since I don't have one). On my Kindle 3, my homescreen looked something like:

[Collection 1]
[Collection 2]
Book #1 (not in any collection)
Book #2 (not in any collection)

Once I finish reading a book, I file it into a collection and it's off my main list view, so all the books which are on my homescreen and not in collections are books I haven't read. I've successfully ported all my books over from the old Kindle to the new Paperwhite, but all I see on the homescreen is:

[Collection 1]
[Collection 2]

I can only see Books #1 & 2 if I sort by author/title or if I search for the item. Is there something obvious I'm doing wrong, or any way to revert to the previous collection behavior? Thanks!
