It would be nice if there was an option to select if you wanted to output the STL as your work document units of measure or something else. I use Slic3r (not sure about other slicers) and it requires mm units however I design everything in inches. Having to go change my units of measure back and forth in the work settings every time is really a pain especially if I have a minor change hear and there I need to make after I already exported the STL.
