Piano roll with user definable note names and colours.

I think it would be great to have the piano roll to have user definable note names and colours.
For example: If you are writing music with 15 tones to the octave you could do away with the piano keyboard, have each note lane have an individual colour, and be defined as a number, ratio, or letter with non-traditional accidentals…etc. Even be able to adjust the distance between intervals . Or if you want could still have the keyboard view but each note labeled as one requires. A lot of this can be done in Melodyne and Reaper.
