And if the numbering would adjust accordingly for key changes, that would be excellent.



Thanks for mentioning that. I would pretty much expect that if the feature were incorporated that it would, but it should not go without saying.

Beyond that perhaps even allowing something in a minor key or modal key to be done in its relative major key. That is something in Am could be done in the key of A with the note A being one, or it could be done in the key of C with the note A being 6. ( For those of us who tend to think in terms of modes more than in terms of keys )
