This is great! It would be really useful to be able to select and deselect notes on the top piano to construct new chords based on these ones (and it could detect when you've constructed one it knows). Showing the sheet music of the chord in the top info box would also be very helpful. A list of similar chords links in the chord info box would be neat. An "automatically play chord" option would make it super easy to find a chord you want by sound. Possibly out of scope, but it would great to be able to put in a sequence of chords and see things about the transitions, e.g. notes in common.
