As a student I would like to be able to display two complete pages on my screen at once so that I can play longer passages without having to click the page turn button. I do not always want to have SmartMusic playing along with me when I'm practicing.
My precise scenario for this is the case where my whole band is on a zoom session, muted except for the conductor. I'm playing along with him on my part, and I can't synchronize the playback precisely with the conductor so I have to turn pages manually... but sometimes there isn't a good spot to do that on a single page. Adding "advance one page" on a 2-up view gives me twice as many opportunities to find a good spot to stop playing and turn the page.
