Feature request: Piano roll indicator NoteSeq

[Coirt]

How would you feel about adding a darker colour to the grid on NoteSeq to indicate black keys or maybe changing the colour of the blue marker box for black keys? As is it's a little hard to figure where you are on the grid. Perhaps a small piano roll at the side.

Could probably do a better job here's a quick one. Makes it easier to lay notes out already.

i like the look of this last screenshot but I don't know if I want to do that. I don't really want it to look like a piano roll but I get the need. I really like the more experimental functions, like random notes and shifting notes. So I don't know maybe. I don't think it would be a hard change, maybe only svg.
