This is very nice.

If I might add a suggestion, it takes a while to fine the number of the chord. For example, if I'm trying to figure out what 1-4-5-1 would be, I have to hunt until I find the 4 and 5. Would be cool if there was another view that was the Nashville number system in sequence to make it quicker to find.

For example:

1 2 3 4 5 6 7

C D E F G A B
