I think you should be able to pick your top three most-used colors to be displayed but then have the ability to scroll for faster color change. Often times when I am taking notes in class, if I want to change colors, having to open the whole folder can get me behind. While this doesn't seem like a huge deal, in college-class note-taking, every second counts and even if you miss one small detail, it can cause issues. This would be really really really helpful!
