Hi Burr,

I've tried that before long ago but it doesn't work very well to have one point suddenly shift from the rest, it makes for a noticeable shaping change in the sketch curve right at that spot.

One kind of vague idea that I haven't been able to explore so far is something like a curve airbrush sketcher where you could lay down multiple strokes and also erase areas and make a smooth curve fit through the densest zone.
