[Feature Idea] Automatically generate modal chord pages for given scales.

[Sintrastes]

Oftentimes when learning a certain scale, even if not particularly interested in the modes, a user may want to learn those mode shapes anyway to assist in learning how to play the scale they are interested in up and down the neck of their instrument.

For this reason (perhaps based on a simple algorithm based on "reachability" of the notes), it would be nice if we could automatically generate scale pages for the user for each of the modes shapes of the scales they are interested in in order.
