Somebody reported on Sourceforge [tickets:#334]:
I'm generally impressed with with what you have done so far, and am a string supporter of yuor project!
However, I can't find a way to insert or remove an anchor point from an existing line, or area.
I think this is < fundamental editing task in a mapping tool like this.
I also urge you to find a better way of doing this than OCAD, which is really clumsy on this point. I am much in favor of the Adobe Illustrator way.
