Small Request

 From:  Ken (JWLRYMKR)

I would love to see the option when making circles to have the ability to plug in the diameter rather than the radius.
As a jeweler, I'm used to working in millimeters with 2 decimal places and math is not one of my strong points.
Also, is there any type of Cap or patch command in Moi?

Regards,
Ken
