Yes, ideally it would. However, we sometimes get stuff handed to us in a few minutes before we start, and I don't have time to get it all cropped properly using the editing tools. So, the zoom control at least allows for getting it "in the ball park" until there is time later to do it the right way.

When you say 'handed' to you, in what format? Presumably, it's a format that you are going to import into MS, then Mike is right in saying to use the auto-crop feature, that should get you into the same ballpark.
