There is also a "pop out" version of the notation. I mentioned in a recent YouTube video I made a few days ago about GuitarTricks that you can pop the notation out, then refresh the page and get the scrolling notation back and have both. It does help to have a large monitor or more than one. (The video has some other tips as well). 

Also when you are on the full performance or the jam along the lower left area has a "Notation" tab that is a manually scrollable version of the entire song. I mention it because I missed the fact that it was there for a long time. It also behave a bit differently. When I resize the pop-out window it scales up and I have to manually scale the window down. The notation window from the left doesn't do this and I can see a lot more of the notation on a full screen. I also finds this view makes for a better destination for taking screen shots and printing.
