Just discovered this, pretty essential plugin if you ask me! Thanks Tyglik!
I was copying curves to Rhino and back as well, far from ideal workflow.

The problem is that I have to offset a lot of curves for the project I'm working on. The new curves always have a lot more control points than the original. The next one even more than that.. So big timesaver for me here.

Two questions:
1. Will rebuild curves (planes?) be part of the 2.0 release? I think it's pretty essential, don't know how important it is for all the other users.
2. Would it be possible to have offset rebuilding curves as standard behaviour? So if you offset a curve with 5 control points, you get one with 5 control points as well - at the corresponding locations? Maybe with a "auto, exact, ..." option?

(BTW, haven't been behind my computer for a few weeks, so first days with the new beta and i love it!)
