Show & gray out notes

Hey everyone,
These are two fairly related features I’d love to see making their way to Cubase.

  1. Showing all notes on the piano roll, not just Cs and
  2. The ability to gray out notes that are from a different key.
    Especially #2 would be absolutely fabulous for quick reference and checking.
    Please, FL Studio can do these, I am sure these can make way into Cubase to make my work within even more efficient.

Are you aware that you can color the notes (but not the keyboard itself) based on the Chord Track?
