It would be great for those of us who work interchangeably in miles and kilometres to be able to switch between the two units without going into settings every time.
Would it be possible to implement a small toggle switch somewhere, either on an activity page, or constantly available on the blue dashboard at the top of a page?
This would mean you would not have to navigate away from an activity to change units. Other units of measurements would stay the same based upon your selection in the general settings...
