I propose to add a world generation option that allows you to choose where the world's center (0,0) will be.
Spawn - The default, the center of the world will be in the center of the player's spawn radius
Nearest equator - The center of the world will be at the closest equator from spawn
Nearest pole - The center of the world will be at the closest pole from spawn
This option will allow players to make symmetrical worlds with 1 equator and 2 poles, or the opposite, without having to spawn at the equator or pole.
