This simple mod disables the annoying "Experimental Features" advice that appears every time you create or load a world with custom dimensions or world settings. You can use it if either this screen annoys you as much as it does to me or you are creating a mod with custom worldgen and you want to disable the advice screen (Jar-in-jar if that's your case!). Compatible with all 1.16.2+ versions, including prereleases!
Although this is a Fabric Mod, it does NOT require Fabric API.
