100% zoom BUTTON for node editor / zoom to standard font size

Using the HOME button to Show All in the node editor gives me 'wayyyy too much border around the node network.

I propose a button visible/accessible in the header that would result in a 100% (as defined by the font size) zoom, centered on the current center of the window.

IOW, when pressed the window would zoom to the degree that the text on the nodes are displayed at the same size as the text in the rest of the Blender UI.
