Knob size not intuitive

[tobiasbp]

I do not understand the setting "knob size". Maybe it could be "Arc radius", and the arc would be used as a reference. In the current version, I do not understand what the reference is (knob size).

OK... I understand now: "Knob size" means "Knob radius" with "Knob" meaning the offset from the center of the scale. Maybe it should be called something like "Center offset", "Distance from center" or something else? Also, the value can not be set below 10 which appears to be a bug.
