(Instantly) closes the loading terrain screen on world changing
Say goodbye to seeing the loading screen for 2-5 seconds when joining a server or switching worlds Since 1.18.2, the client only quits the world loading screen once the chunk it is in has been received... and at least 2 seconds have passed.
By default, the mod fixes that behavior. Additionally, you can also fully get rid of the screen. This mod also happens to fix an infinite-loading issue with Sodium on Paper servers on join/respawn.
Yeeting the screen entirely
If you want to fully kill the screen, you can toggle a config option (you need modmenu and Cloth Config API for that). Keep in mind this reintroduces a client bug where you can briefly (only visually) fall through the world if your network connection is slow or the server is loading chunks very slowly after a world change.
Here are video comparisons of Vanilla vs. the mod with the instant-close option enabled:
Server joining (1 vs. 3 seconds)
World changing (0 vs. 2 seconds)
