Not sure. How will this work for lines/boundaries? Would one need to
specify line's vertex coordinates? In crossing lines and common
boundaries there are shared vertices (nodes) - what then?

What with points and lines over areas? Or would only the centroid
location = area feature location?

Thanks for developing v.edit. It's a power tool.

Cheers,
Maciek
