"Color notes" in staff/part properties
I think it would be useful to have a "note color" option under the "staff line color" in the staff/part properties. It would allow us to distinguish staves more instantly and avoid us to change note colors each time we make an edition.
A second option would be a drop-down menu with four choices, one color for each voice. That way, the notes would be colored according to their assigned voice (as the plugin "Color Voices" does but not applying to all staves/parts of the score) in addition to their assigned staff/part.
