Scaler is a great piece of software. I like it so much. By using it, I now have several suggestions.
1: When the mouse is placed in a Scale and one Scale is selected at a time, it is recommended that Note of Scale be displayed in different colors on the keyboard. For example, I chose Cmaj scale, and the keyboard on it was marked C D E F G A B in green. Now there is Listen note of scale, which is very good, but to be more obvious, I hope that the mouse will display in different colors.
2: I hope the prompt keys on the keyboard can make the color more bright. Now it’s blue and light blue. Sometimes it looks a little difficult. It’s better to choose your own color.
