Offset Segment is one of my favorite tools. It's like a semi-automatic copy segment tool.
I'd like to suggest that options be added to the Offset Segment Options dialog to allow multiple copies in the same fashion that the Move command does.
One copy is the default now. Continuous copy may not make sense. Repeat and Multiple Copy, would definitely be useful.
Another feature that would be useful is the fact that an offset can be made OFF the face of the object in space. If one could lock the movement of the copy to an axis perpendicular to the active reference plane by pressing the Ctrl or Cmd keys, that would be useful.
