About this Mod
This mod simply adds a command that allows you to turn a map(either filled or empty) into a map with ID specified.
Same function is provided by vanilla data command, but much more complex and requires very high privilege.
This is especially useful when you use a multiworld mod like my Combinedworld, if you made a map decoration and don't wanna do it once again in another group of worlds.
Also, lost maps can now be re-discovered by travelling through all the IDs (quite hard though).
Hold a map(empty or filled) on your main hand, use the command and it turned into desired map.
You must know what you want, though.
