Custom world preset

World presets can be chosen in "World Type" button in "More World Options..." screen in "Create New World" to determine what dimensions the new world has.

Usage
When opening the "More World Options..." screen for the first time, the "World Type" button is displayed as "Default". In this case the new world does not use any world preset, but will use the three vanilla dimensions by default, and tries to read the dimension files from the dimension folder of the data pack. In this case, you can modify these three dimensions or add new dimensions with the dimension files, but you cannot delete these three vanilla dimensions.

Once the player clicks the "World Type" button, the game will use the world preset to determine the dimensions of the new world, no longer using the dimension folder. Changing the button back to "Default" will use the world preset, instead of the original default state. However, without the data pack, the default state is exactly the same as the "Default" preset.

The game also does not use world presets if custom world settings are imported.
