About
A Fabric *.21.11 client-side mod that detects and inspects any opened inventory GUI, capturing titles, slots, item names, lore, NBT, custom model data, and enchantments. Saves captures as JSON/YAML to .minecraft/copygui/. Features a capture button injected into every HandledScreen, a full GUI browser with search/filter, a slot-level preview editor, and /copygui list/open/export commands.
