I've been having trouble telling whether a note I hit is late or early when in mid song. It is kinda annoying to look down at the accuracy bar at the bottom to check if I am hitting it too early or late, especially when streaming. I think it would be a good idea to give different colours or to some how change (or give an option to change) how the 100/50's look. So, if it hit it too early it will be blue and too late will be red or something. Looking at the bar at the bottom is hard mid stream. Just a thought.
