I wanted to hold off on my suggestions until I got a better list of improvements, but this guy gets it. It is so annoying about the section and not the notes needed to riff repeat. All too often, there is a huge space in bass sections that are breaks, or long single held notes before the start of the section needed, but it only contains a small portion of the "tricky section".
Another, A way to review. Sure, if you are using Riff Repeater, you can play it again another time to see what notes where missed, but if you are just doing a play through, there is no easy way to review or see what was scored as wrong.
To add to that is some way to say, "why it was wrong". Fret too high, fret too low, (something dumb like that or wrong string) but also, the bends. Why was the bend or slide not scored or registered as correct. Not bent far enough? Over bent? slide too soon? too late? not far enough? all frustrating parts that often take repeated guesses for a beginner.
