Undo in Digitize Contours

[sinc]

Digitize Contours needs the ability to undo a step, similar to when you're drawing a polyline.

don't digitize contours, enter them directly as
polylines, as when you convert them to contours
and or use contours in your terrain model you
will need to make the same contour weeding choices.

I'm all for that (not using "Digitize contours" that is). Seems so much easier to just digitize the polylines and then set elevations to them. Of course I have a kick @ss program that makes it real simple to add elevations to polylines in sequential order with a whole lot of other features also.
