Basically that.  I like using staff view so that I can 1) read my note data as notes and 2) play along with it while I record on other channels.  Usually doing things like building up my ensembles one solo instrument line at a time...
 
Unfortunately, it won't scroll the window until the cursor fully exhausts what in view.  I would prefer, for reading's sake, to have the window scroll after the cursor gets 80% of the way across the window.
 
Any way to make this happen?  Obviously it works this way in PRV but I wish the staff view would work similarly.

Unfortunately, no, and I've tried a bunch of crazy ideas to try to fool the staff view to "page turn" earlier (haha, including nodding my head). I use dual monitors, and the switch from extreme right at end-of-measure to extreme left at beginning-of-next measure is a whiplash inducer, fer sure. I also, on occasion, use staff view in a live situation (single monitor laptop), which is sorta _okay_ for songs I'm familiar with, but if somebody requests, say, "la vie en rose" (which I actually have a midi for somewhere on my laptop), I'm going to fluff a few notes waiting for that darn last measure to flip--and forget trying to read any up-tempo tunes!
 
I did "feature request" this (configure when the staff view pages ahead) in the past, but it's been a while. Thanks for the reminder, I'll request it again. You can, too!
