I have an idea that is related, so adding it here. The problem I have in BandHelper with the paging function is that when you get to the last few lines of the song, the page does not jump those lyrics to the same spot. I believe you could easily resolve this in the app by adding dead space to fill an entire page at the end of every lyric document. this way, the last three lines of a sing that happen to have their own page would still scroll the 90% and be where you expect them, instead of somewhere in the middle.
And thank you SO much for saving me from OnSong. Not sure where to post kudos on this site, but I have about 15 pages of great things to say about bandhelper.
