I would like to be able to view scanned copy of my score
in JEdit or in a panel while being able to enter notes at
the same time.
This would be much easier to enter scores as you only
need to look at your screen when u input the notes.
The image might be view in the background behind the
editor, but should have options to scale and maybe
rotate and dragged around.
To expand on this idea further, it can somehow be
turned into a manual OCR. Lines of staffs can be position
and notes can be click to input position of notes.
