I seem to recall a request made here for the galley view not to scroll so far over when moving to a new page. I thought that the ability to see more of what had been written in the previous bars was something that the developers agreed to provide. At present, on can see nothing to the left of the new bar. Apologies if my memory is faulty in this matter; but I am frequently having to move the window across to see what I just inserted.
On the other hand, maybe what I want has been made an option that I havent been able to locate in v. 4.0.
