First of all. What joyful news when I read this on the iPhone that this software is now available for the Mac!!! Of course I bought them immediately.
I also have a wish and a feedback for you.
Graphically, I don’t like the circle of fifths at all. Can’t you create it in a similar way to this one: https://felttip.com/5ths-Opus1/
This one is not so overloaded in colour, you can see the scales (with roman numerals) and it looks clean. That would be my only wish at the moment.
Many thanks and best regards
