auto-scrolling while editing

[Bric]

Sorry if this has been asked before

By default, when i start typing into a blank new score Denemo starts 
autoscrolling as soon as I fill measure 1, at which point it hides measure 1 
out of view (!) and cursors into measure 2. A bit frustrating.  

I want to be able to type a few measures and keep them in view, until 
absolutely necessary - until i have filled the width of the screen with 
notes/measures.  

Ideally (i think), when I hit the right edge of the screen, it should 
autoscroll such that the cursor is close to the left edge, but perhaps not 
flush against it. Maybe leave one filled measure to the left of the cursor, so 
you have some visual continuity.

Is there a setting in the preferences to control this?
