Make auto-zoom an option

Once you know what you are doing, the auto-zoom that happens when you create a new flow gets in the way. Example: I have the canvas the size that I want it and at the location I want it. Good. Next I create a new flow and the view auto-zooms onto the new flow. Argh. Now I have to reset the size and position of the canvas. That just gets in the way. Please make auto-zoom an option we can turn off.
