I'd like to see an Imperial selection available for those of us across the pond that still use it. Everything I load comes in converted to metric.
I looked in the settiings.ini but didn't see anything obvious that would make it load into Imperial either.
Also, looking at the Help portion it still shows I'm on ver 4 build 0, but I see the latest release was 03-15-2013 so I know there must be something like build 0.xxx.

Great work! Keep it up!
