Hi Felix, I haven't started to work on the Match command yet so it is not easy for me to make any preview images of it yet.

But the Match command will work by modifying a full underlying surface, it won't be able to process an edge that is not aligned to the natural UV structure of the surface. I'm not sure yet if you will have to pick an edge that is a natural edge of the surface or how exactly it will work.

At some point in v3 I also do expect to update Blend to allow it to work on a longer chain of edges instead of only between 2 edges at a time.
