NAME: Slimefun Customizer
LINK: https://www.spigotmc.org/resou…limefun-customizer.49012/
DESCRIPTION: Allows you to add your own custom items to Slimefun via a GUI.
Also allows for custom item names and lore with color codes.
Even though this is kind of outdated, it can be edited via
the source code on GitHub or whatever its called I think, so it's not completely dead.
