In addition to previous function you can enter co-ordinates and it'll teleport you to somewhere in that chunk.

Main desire for it is to find and travel to chaos island more easily.

Should probably come with a config option for which dimensions it'll work in.
Maybe handle cross dimensional teleports by selecting a dimension from already established teleport points saved in it.

The reason something like this has not been added is it is too powerful and can be abused in too many ways.
