I vote for vertical scroll bars. I asked for it years ago (well, it seems like that), but they haven't eventuated yet. Without vertical scroll bars, you don't know where you are within the code or what proportion of the total code is taken up by the visible area. You can't scroll without losing your selection, unless you want to spend ages scrolling around with the mouse wheel. And you can't scroll quickly to other parts of the code if you have an error and the section shortcut menu is missing.
