This system allows developers to create personalized creative menu tabs with custom branding, background colors, and item lists. The configuration file must be located at assets/corewithstuff/cws_tabs/tab.json.
Template Example (162x16, 180x16 recommended but can do any size, creative tab will squish it to match 162x16 though)
