Numbers instead of colours is a must for piano.
People learning piano are used to numbers instead of colours for finger selection. Using colours when you are used to numbers is quite confusing.
My son has been taking piano for 5 years using the number system. He immediately went to the mode with black notes because the colors were distracting. But then, he doesn't have any hints on using the correct fingering.
I gave 3 votey. Some people are colorblind too. I always have to ask someone to check the right colors.
As far as I'm concerned, coloured finger designation ranks right up there with dinosaur pictures beside the score... fun for 7 year olds, but seriously annoying for 47 year olds.
Not only would it be practical to have the finger numbering beside key notes (and I mean key, not ALL), but it would also be nice to see a separate stream for technical skills like knowing when to skip or change fingers, based on where the phrase is headed.
It would be nice to have an option in settings:
number on all notes
numbers only when it make sence
We all can count to five on our fingers and instinctively know which number is for each finger, but colours have to be learnt.
Love it I hate the colours when learning guitar !!
