Utility mod that fixes player's keybinds and settings being reset whenever the pack updates.
All the mod does is just copy all of the files inside of the /config/yosbr folder to the root .minecraft folder if said file doesn't exist when the game launches.

Alternatively, there's also Configured Defaults that essentially does the same.
