There used to be a way - I don’t remember how long ago - to split the arrange window in to 2 panes and scroll each independantly, mostly I think to keep certain tracks visible while moving through others.
Similer to what can be done now in the mixer.
I’ve searched the manual and clicked all over the arrange window . . .can’t find it.
A problem can arise that if the screen is split, but one accidentally moves the split point to the top of the window, it “disappears” but it is there, one has to place the pointer right at the top and click and drag down, I did it a couple of times and head scratched, but that was the solution, hope this helps
