Piano chords and transposing instrument

[brskaylor]

I *think* what you're saying is right, but let me give a more explicit example to make sure we're saying the same thing.

Here's an untransposed song with the piano chord diagrams:



Here's the same song after I used the transposing instrument function to choose Bb:



As you see, the while the chords of the song transposed (correctly), the piano chord diagrams remained the same. I would like the piano chord diagrams to transpose so that in the second photo they would show Dmaj7 instead of Cmaj7.

I have the same exact use case as described in this thread. As a trumpet player who thinks in piano, I'd love an option for the on-screen piano during playback to transpose as well.
