This mod lets you save the coordinates of your current position and retrieve them later on via commands. You can give your positions names and even add them to a custom list! If you want to get a previously saved position, simply search for its name, list and dimension and retrieve its coordinates in your chat. All positions are saved to a JSON file, so you have total control over your data. For usage instructions please consult the wiki.

TLDR:

Saving position:

/pos set <dimension>.<list>.<name>

Retrieving position:

/pos get <dimension>.<list>.<name>
