I'd like to suggest that you add an option to turn on and off the Labels for each photo in the Enterprise Edition. Furthermore the option to hide the option to display the labels would good. This is similar functionality to the ability to display/not display the clock and calendar.
These options are available in your opposition's screensaver creating software (2flyer screensaver builder).
A second suggestion is two buttons on the 'About' display. The first would display the 'License' info the creator has added and the second the 'ReadMe Text'.
