RotateBook
Whomever wrote Copperfield, the Newton’s built-in book reader, was being pretty lazy when they realized that they would have to support multiple book orientations in NOS 2.0. So they just made the Newton give up with a silly error message.
RotateBook is a patch for the book viewer. If you attempt to open a book that won’t fit your current screen orientation, it will rotate the screen for you and then open the book.
This package only works with NOS 2.1.
