Lite version crippled

While the free "lite" version has most of the buttons that the full version does, nowhere does it say what the limits are. This became frustrating when trying to decide whether to purchase the full version.

It seems (trial and error) that you can put in only 10 books, and the email export features instead quit the app completely (not even a polite "this feature only works in full version, would you like to upgrade?" message).
