Chord symbols input from MIDI keyboard

Hello,

I know, this is already possible in Finale or Sibelius.
There are a lot of scores, chord charts that can be more and more speedy with the ability to input chord symbols from a midi keyboard.

I imagine that after cmd+K command could be possible play on midi keyboard and input the correct chord symbol.
An option dialog for decide interpretation, options for tell to the software the various voicings versions and a key command for change diatonically the chords already written.
This is a feature that made me simply life when I tryed Sibelius and I think that can be a serious timesaver in Musescore, instead of typing all chords manually in large scores or charts.

Thanks ;)

Tommy
