WTP What's This Pack Mod 1.8, 1.7.10, 1.7.2 is a simple modpack identifier for those of you who make modpacks and would like your users to have that extra bit of pizzazz in their pack. All it does is writes a string in the upper left corner of the main menu. The modpack name and the color of the string are both customizable, and this can even be used to throw a little message to your users.
