Let the vertical positions of staff lines be fully customizable
It's really great that you can customize the number of lines in a staff, and the distance between them. But this assumes that staff lines are always the same distance apart. There's not a way to have a staff with different distances between staff lines, as they are in some alternative notation systems like Klavar or TwinNote .
To support these kinds of staves, it would be great if users could place staff lines at any vertical position. In other words, have each vertical position of the staff be customizable to be either (1) a line, (2) a space. And while we're at it, (3) a ledger line.
Thanks for considering this. I realize it is a non-standard feature.
