I'm sure it's been mentioned but I would rather have a list of folders on my homescreen than books.

I use my Kobo for school mainly and it would be nice to have all my books in folders for each class that I'm in. Tap folder, see book list, pick book.

That would make it a lot easier for me to keep my personal, fun reading separate from my school reading as well. My Aluratek LCD e-reader let me organize all my stuff into folders and it was a very handy feature.

Also, maybe an option to extract all highlighted text for books on your device. (including sideloaded books)
