Theoretically this mod supports ALL modloaders!
Introduction
In 1.19 and newer Minecraft versions, Minecraft will automatically open the "Create New World" screen on clicking the "Singleplayer" button if there's no existing save.
The process above might be very slow if many mods are loaded, resulting in users who mistakenly touch this button having to wait a long few seconds.
This mod lets Minecraft display an empty world selection list screen even when there is no existing save, like in versions prior to 1.19.
