Default World Type
by MelanX
With Default World Type, the world type preselected on the Create World screen can be set to a chosen value, so new worlds start on it without a manual change.
What it does
Default World Type changes which world type is selected by default when a player opens the Create World screen. Setting it in the client config to a value such as skyblockbuilder:skyblock means a new world starts on that type without the player touching the world type option, which lowers the chance of accidentally generating the wrong world.
Only the player's game needs the mod, since it is limited to the client. For servers, the right server.properties file should be supplied instead, or Default Server Properties can handle it. Once a player enters the Create New World screen, the mod writes a file listing the allowed config values.
Files are published for Forge and NeoForge across 33 release versions, 1.14 – 26.3, with 1.20.1-4.0.5 for 1.20.1 as the latest Forge file and 26.3.0 for 26.3 as the latest NeoForge file. The code is under the Apache License 2.0, and it is open source.

Use cases
Modpack defaults
Modpack creators can make a pack's custom world type the default, so players do not have to pick it on each new world.
Skyblock packs
A pack that uses Skyblock Builder can set skyblockbuilder:skyblock as the preselected type for new worlds.
Who it’s for: Modpack creators are the main audience. Players who create worlds on a pack that uses a non-default world type also benefit from the preselected setting.
