To be honest, Dennis, I am only interested in basic lead charts anyway, rather than fully written charts. Wouldn't use those even IF I had them!

I would have thought that, as long as there is a one stave overlap, that landscape mode's no different than paging back for a two page chart... footswitch it down and up, touch the hotspots for a page turn or multi-page repeat... I don't think I would even LIKE a page that gradually scrolled down. Part of reading is jumping from one stave to the next, and for that to be accurate, they have to stay still!

Maybe the developer might implement something like the bottom stave of the first landscape page being highlighted gently, so that when it appears on the top of the scrolled down landscape mode, the eye is confident that it's still the same stave?
