Hi
When measuring distances (shortcut M), it should be a good feature the
measuring box show units in mm and mil simultaneously, independently of
pre-selected default ones.
Altium and DesignSpark PCB, just to refer two of them, do this.
I think this would be a very important detail on your EasyEDA.
Thanks,
