A simple open source addon for the Xaero's World Map, which adds drawing visual chunk-based zones on the map for everyone.
IMPORTANT
The mod is currently in alpha, and at the moment it only works locally. It is expected to have a LOT of fundamental changes internally.
Don't expect a savefile to be inter-version compatible as this is a working prototype - there'll be breaking changes soon.
Don't expect support for other Minecraft versions and mod loaders until it is somewhat finished for1.21.1 NeoForge.
