Emmanuel,

I understand what you say, and moving around is obviously a way. But
think at editing any graphics with an editor, like, say Adobe
Illustrator. I can do both there: I can pan but I can also zoom in
vis-a-vis my default, start up view. I do not really understand why
you consider this as a difficulty...
