view > mm vs inches, and tool size display, in AXIS

This is probably simple but I can't find it through some searching.
My machine is set up as imperial but I do (basically all) my gcode in metric.
As a result, when AXIS starts it comes up in inches, and I have to change it to metric before touching off tools.  Similarly, the cylinder that represents a tool displays in inches so when I change to mm it's 25 times larger than the job and I can't see anything.
I'm using linuxcnc 2.7.14 and would appreciate any advice.
 

Running metric gcode on an imperial machine will result in small rounding errors.

Perhaps you could make a new config that is metric?

Could work okay.

I could totally do that (rounding errors on this machine are so far below its backlash) but then I have to go through all the axes and recalculate steps per unit distance and bleah.
