Darn, for a minute there I thought this app might allow you to add pages to rearrange pages in existing documents like Notebloc. So few scanner apps offer this, but it's super useful.
Edit: BTW I was talking about Android, plus if you read the comment chain below, this one does! Just long press the page number icon and drag to move.
I've read the books several times over, so I think I know exactly what you're referring to. While I agree that you could potentially stretch Dune to three movies, I don't think you necessarily need to for the sake of a movie franchise.
