The scenario I'm imagining is like this: you're drawing, editing, etc, and you want to zoom in on some bit, so you Z + marquee over that area. As it is now, the Magnifier is still active and you have to key press back to the tool you'd been using.
Is there/could there be a way that you have Magnify only while you are magnifying, then returned to the tool you'd been using prior to magnifying?
Magnify should also still be available for times when you still want it, but maybe there could be two key commands for each? One for permanent magnify (until other tool is selected) and one for "magnify on the fly"
thank you
