Independant zoom/resize for Drum Editor and Piano Roll

I would love to be able to zoom/resize the Drum Editor and Piano Roll independently of the other. When in Drum Editor I need to zoom/resize to be able to read the trigger names of the Drum Map. But when I change to Piano Roll Everything is zoomed in and I therefore need to zoom/resize again. Why not be able to zoom/resize either one without it affecting the other?
