CoreShulkers

Stop placing shulkers down just to grab one item. CoreShulkers opens them straight from the inventory or ender chest, while guarding against the same box being opened twice.

Features
• Right-click a shulker box in your inventory, or in your ender chest, to open it
• Contents preview in the item lore (first lines configurable)
• /shulker deposit quick-stacks matching items into the open or held shulker
• Each linked shulker is tracked by ID, and a box that is already open cannot be opened again
• Optional open cooldown, blocking of moves while open, and toggles to disable opening or placing
• World and material blacklists; /shulkers clear turns a box back into a vanilla shulker
• Auto-save every 5 minutes by default; SQLite storage bundled

Requirements
• Server: Paper or Leaf 1.21.11+ (or a Paper fork)
• Java: 21+
• Bundles its own SQLite driver (larger jar, ~12 MB).
