Previously, I could view books on my device and display them in Collections mode so that books that were in a collection would be shown within it and those that were not would be listed after the collections.
I can't seem to do this now; I can set the list to On Device and Books, but the only sorting options I have are Recent, Title, and Author. "Collection" does appear at the bottom of the menu but is greyed out.
Am I missing something, or is this option gone? If it is, it's not the end of the world, but I really miss it.
