Create: Better shops

This mod enhances Create's trading mechanics by introducing the Admin Shop block, tailor-made for administrator-managed server environments. Moving beyond standard shop limitations, it allows for dual-item pricing (requiring two different items to complete a trade) and features a built-in player whitelist system to strictly control who can manage or interact with the shops. Designed to blend seamlessly with Create's signature aesthetic and kinetic workflow, it provides a robust solution for building balanced and secure marketplaces in multiplayer servers.
