How hard would it be to create a tab staff in denemo. Basically this
would be a staff that contains 4,6,7, 8 or more lines depending on
desired number of strings. Instead of note heads and stems it would
contain numbers. These numbers each have a duration similar to the
existing notes. This tab staff would force the tab creation of
lilypond. I think then denemo could eventually support the "guitar
pro" format similar to tux guitar.
