Building Inventory Presets!

Hey! Welcome to my Inventory Preset's Mod! This is mainly created for builders that hate losing their blocks and having to constantly go into the creative menu and get them again. So i made this mod, for example lets say you're buildin in a medieval style, you cn type in chat -save medieval, then once you're ready to start building again, type -load medieval and you will get all your blocks back in the same position!
