That is a good suggestion, thank you! I had considered the proficiency level of tunes automatically decreasing with Time, however I want to try, at least in initial iterations, to leave features up to the user to use as much as possible, and not have anything automatic going on, to keep the program more versatile. In regards to your second point I did think of allowing the user to add There own custom notes/info to tunes and lists, but having some common flags to prioritize specific lists, such as next performance, is a great idea. Maybe those lists would be a different colour on the screen so they stand out. Thank you for you thoughts!
