I (and my wife) are trying to organise our Kindles particularly in the cloud. what we would like is to have four categories: 1. I've read it, she should read it. 2. she's read it, I should read it. 3. we've both read it. 4. one of us has read it, don't bother. I would also like to delete for ever stuff that we have both read and will never read again. Don't tell me RTFM because I can't find anything useful. It would also be good if we could shift books from one category to another. Please does anyone have any ideas?
