There /will/ be work to design something that integrates with key and
mode well.

I suspect that an abstract layer (somewhere, in the UI or in the code
itself) defined as pitch class would be helpful to organize sets of
pitches as well as have some identifier for unnamed collections of
pitches (i.e. scales).

(Some searches on the Internet leads me to find this. I have yet to read
them, but may be helpful)
