Overview BackpackMC gives each player a personal, persistent backpack they can open via command or a configurable shortcut item. Sizes are permission-based (up to 6 rows). It includes auto-pickup, sorting, previews, world/gamemode restrictions, multi-backend storage, and a small API/events layer.

• [] API: 1.20 (Spigot/Paper) [] Java: 17+ [] Core features: Shortcut item (BUNDLE by default), dynamic preview, auto-pickup, auto-sort (OFF/LIGHT/AGGRESSIVE), clean/sort commands, world/gamemode restrictions [] Storage: YAML, SQLite, MySQL + built-in migration [] Safety: Cancels duping interactions; sanitizes stacks on snapshot/save [] Localization: en_US, de_DE with auto-merge of defaults
