Quilt Loading Screen is a 1.18.2 mod for Quilt originally created by @darkerbit and now maintained by yours truly.
It’s pretty self-explanatory; some patches fall from the home screen to give you a nice sight while your mods are loading.
Every June (or toggleable on during any other month) Pride Mode turns on where the solid-colour patches are replaced with pride flags!
It also contains a neat little resource pack (disabled by default) by @Octal which turns various UI elements into the Quilt colours, as well as stuff like hotbar Quilt patches.
You can download it from Modrinth at Quilt Loading Screen - Mods - Modrinth.
