HUDCreator — Create Shops, Trades, Kits & HUD Overlays In-Game

HUDCreator is an all-in-one Forge 1.20.1 mod that lets admins create and manage interactive interfaces directly
in-game: shops, item trades, kits with cooldowns and persistent HUD overlays — all without external config files
thanks to a full in-game editor and an embedded web dashboard.
