Hmm. I'm not sure if it was dynamic map or what. The server I was on that had one basically had a map with different colors for different biomes. I have seen some that show biomes in full detail as well as details like buildings in them which I think is the dynamic one. I more meant the different colors for different biomes not sure if that's a diff map or also a dynamic map. The owner only called it a biome map so I'm not sure.
If that's not possible currently the teleport signs for different biomes would be useful as well.
