In my opinion, if you use the viewfinder, you are already at the top of the game. I try to aim for pages that work well on a 1024x768 screen, given scrollbars and toolbars, and more. It may be worth changing the screen size to 1024x768 (or at least what you support) from time to time to fully understand this user interface, but overall the window size allows you to know quite well.
