It's a pointless feature since its only function is just posting a map grid of size without typing the numbers in yourself. I found it just be a far more advance and far pleasing to have a true duplication. I have a good map. Just need to change two things to make it impressive. Sure: I can copy and paste everything onto the second map, but this deletes the purpose... again... of a duplicate button. It be great if a true duplication be in place.
