I want a plugin that's capable using copies of other villages and positioning the parts so it looks natural (And you don't copy the village, the plugin has a bunch in its files). Plus the villagers, but if MCEdit can copy entities, I don't see why a plugin couldn't. Anyone willing to make this?
You want a plugin that takes a village from a file, puts it on the land, and makes it look natural? Ptsh, not likely. The best way to do it would be to use some sort of village generation, but I'm not sure there's such a thing.
