You can specify both imperial and metric jog increments in the ini file. It actually works to have 50.0mm, 1.0inch, 0.5inch, 10.0mm 5.0mm, 0.1inch, 1.0mm, 0.01inch, 0.1mm, 0.001inch, 0.001mm and those measurements will be displayed and jogged regardless of the G20, G21 state.

(and was wondering why you > cared, but assuming "each to their own") I am at least as much worried that the metric user can jog .2mm's and get .2mm's. Both according to the DRO, and a metric dial indicator, which I don't have one of. On this side of the pond, its inches or get out a calculator. But if its machine units, the metric user might want to up the size of that string of setp's just to get a minimum jog that isn't polishing the hubble mirror to the wrong curve. :) But that still doesn't make a multilabel work.
