I def like the string-to-wheel layout. Putting in melody lines and power chords are easy. I call it good for a beginning guitarist because the tabs for all the chords are printed out. What would make it better would have the option of either the tabs of a chord or just the chord name and a way to mark the number of times to play that chord, like a line that fits in the middle of the tab staff. I think that would be a good mod.
