I just want to be able to mine undisturbed by monsters and I want to be able to make my own mines, not have big holes in the midst of my strip mining, When I remove caves from the mining file it still spawns holes, and I dont know how to remove all the airpockets.

I just want a data pack that disables caves from generating and monsters from spawning

Alternatives for this would be:

1. Configurable menu inside the game, like it used to
2. Downloadable datapack

You can do these datapacks on your own. This mod just adds the dimension and the teleporter itself.
The datapacks on GitHub are just examples to see how it works.

But how I.. ok
