I am really loving HP, iti is a fantastic tool!!!
I want to know if it is possible to export the music in you format (i.e. exactly how I see it in the screen), I found fantastic to play it that way, it is a kind of “piano roll”, which is fantastic specially when one is not so good reading music score.
Long time ago I learnt to play using a method called Ambros tabs (http://www.ambrosepianotabs.com/page/introduction) could be fantastic if I just could export as PDF the view you called expanded, in a way similar to ambrose tabs, I think it is easy for you, because the visualization is already there it is a matter of exporting as pdf.
