Seeded Dimensions - 
This mod simply adds in a config to set the seed per-dimension.
Config
// Located at config/seeded-dimensions.json
{
"minecraft:overworld": "default",
"minecraft:the_nether": "default",
"minecraft:the_end": "default"
// "NAMESPACE:DIMENSION": 2
}
You can add any dimension to this list, use "default" to use the default config file seed, or set a number for a custom seed.
If you run /execute in ... it will auto-fill what dimensions exist, that tag shown is the tag that should be in the config here.
