It might be worth reconsidering the traditional concept of "a page". The iRB Player already has the ability to scroll longer charts, yes? Allowing an unlimited number of lines would eliminate the need for multiple pages, or short bars to squeeze tunes into one page, which makes the chart harder to read. There could still be "page break" indicators for printing hard copies. Mobile devices have revolutionized how we read books and listen to recordings. Maybe it's time for "sheet music" to evolve too.
