This sounds like an app issue. I doubt changing tablets will help on this one.
I currently have a Nook Tablet which I find is becoming increasingly difficult to manage as far as my library goes. I've spent hours trying to organize my books, creating shelves and such, but the more books I get, the harder it becomes to keep everything straight. My Nook just isn't capable of doing what I need it to do, and with over 300 books in my library, it's just becoming a bigger and bigger issue.
I'm hoping there is a tablet or app out there that will let me do the following:
1. Mark books as read/unread.
2. Easy way to create, manage and sort shelves
3. Ability to add shelf shortcut or folders to home screen
4. Ability to see book summaries for ones that have been downloaded (I use Calibre to organize my library so I know the summaries are THERE ... but you can't see them once I put it on my Nook.)
Is there anything out there that can do these things??
