Hello guys.

I think it would be a good idea to add bright and darker areas in the Piano Roll for white and black keys to better distinguish them.
Most DAW has something like that. Like FL Studio or Ableton.
When in Piano Roll we create melodies and press play, there is a small triangle on the top that follows the notes but there is no line, that follows the notes.
Something like this is in the Song Editor but not in the Piano Roll.
I chime in with this suggestion :)

Additionally would be great to have (like I've seen in other DAW's) to replace the labels of the keys for certain tracks.

E.g. showing "tom1", "tom2", "bell" etc. instead of C, D, E for a track containing a special percussion soundfont
