Smart Stack Refiller

Smart Stack Refiller 1.1.0 for Minecraft 1.21.11

Improved

• Improved refill detection when placing or using items very quickly.
• Refill logic now detects when the held stack becomes empty instead of relying on an exact 1 → 0 item count transition.
• Added a short refill cooldown to prevent duplicate refill attempts.
• Improved drop protection to reduce accidental refills when intentionally dropping items.
• Matching stacks are now compared using item data/components instead of item type only.

Fixed

• Fixed cases where fast block placing could fail to refill the selected hotbar slot.
• Reduced repeated refill checks when no matching replacement stack is available.

Technical

• Migrated the codebase to Mojang mappings.
• Cleaned up obsolete tracking logic.
