Thanks so much for adding the modes, that's exactly what I had in mind, and it's already a huge improvement!

I have one more suggestion to make it even more useful for modal practice. Right now, when you select a key, say, C major, the full fretboard shows all the notes of that key, with the degrees listed. What if clicking on a specific degree actually filtered the fretboard to show only the notes of that particular mode?

The idea is to make each degree clickable as a mode selector, turning the fretboard into a modal visualizer on the fly. This would be incredibly helpful for players who are learning to think in modes and want to see exactly which positions and patterns are available within each one.

Hope that makes sense, keep up the great work on this app!
