A 'Practice Sight-Reading' mode of operation:

After a two bar metronome count-in it blocks out (white's out) each bar in turn, so forcing the eye to keep moving forwards through the score. Thus by the end of a page it's all white. (I accept it may be necessary book mark individual bars or something similar, but who knows?).

This would be pretty difficult to implement correctly as I would have to determine exactly where each bar is, how wide, how tall, etc. I'm not sure I can add support for this feature anytime soon, but I'll keep it in mind for the future.
