Absolutely, you're totally right about the learning mode. I've got that request a lot since I released it and I plan to build that in once I build some more modules: A spaced-repetition based module that teaches you the notes a few at a time. Kindof like Duolingo

The reason why I didnt make it is because I'm an intermediate player myself and I guess right now it resonates with intermediate players who mostly kindof know the notes but have a lot of blind spots. While the feature you requested is more targeted towards newer guitar players

Re: Visual vs feel, if by feel you mean sensory input like touch and how the guitar strings feel? yeah, I totally agree. Except I cant build software to replicate that so this is about as good as it gets . That said, I still find it very valuable for making visual connections for notes and intervals

I was going to say the same thing! I guess tutorials could be a first step before jumping to the quiz part.
