> Surface-to-surface Flow is a somewhat different story, where the "parameterization" of the surfaces do come into play, so those can be affected not so much by just control point counts,


Michael, I did want to ask you about that:

Is it possible to add an option where the new line (curve) could be made with control points matching the original curve, but straightened out?
Of course, the only purpose the control points would serve is to match "parameterization" when extruding this line to make a reference surface for flow.
You may have seen where I've taken this into account when I perform a "flow on revolved surface".

I dunno, just a thought.
