Color notes via right click or add a shortcut to do so

Hello,

We alreay can change note color via the inspector, but for the small screens it would be cool to be able to change it via the right-click menu. In short:
- Select a note/bar or several notes/bars
- Right click
- Color => the "select color" window appears

An alternative would be to have 4 main colors (defined by the user) included in the "color" right-click menu:
- Select a note/bar or several notes/bars
- Right click
- Color
- Select color 1 or color 2 or color 3 or color 4

In addition to that, a keyboard shortcut to color a note or selection or notes (one for each of the four main colors) would be very useful. I would be grateful if you consider this option at least.

Thanks,

creal.
