Same goes for the numeric scale option in the top bar. Adobe, it's the same thing! Activate the proportional link icon by default! What's wrong with you??? It's one click more every single effin time!
By the way, the unit in this input should always represent the one chosen in the ruler or info palette. You can still change it of course but the default should orientate itself on the global option!
