Would definitely like to see customization of the notes displayed on the piano roll with regards to velocity grouping. The current scheme of how the colors of the note change (low velocity: purple, blue, green; high velocity: brown, pink) is quite confusing. A gradient for a selected color from light to dark would make more sense and it would be easier to understand. The current colors also do not look to good on a lighter color theme and would benefit from darker colors instead of the pastel-like ones we are given.
