Smart Stack | 1.21.44/50+

Smart Stack automatically refills your last block/item slot when empty, letting you build/use without interruptions! This addon can't be missing in your world. Compatible with custom blocks and other addons.

Smart Stack is a Minecraft addon designed to keep you in action without interruptions, automatically refilling your most-used items in these scenarios.

• Block Placement: If you place the last block in your slot and have more of the same type in your inventory, SmartStack instantly refills your hand.
• Food Consumption: When you eat your last food item, SmartStack refills it with more of the same type if available, so you never go hungry.
• Mining: When a tool breaks, SmartStack automatically equips a new one of the same type if you have it, so you can keep mining.
• Throwable Items: Whether you're throwing snowballs, eggs, or ender pearls, SmartStack refills your slot so you can keep going.
• Potion Drinking: After drinking a potion, SmartStack refills the slot if you have extras.
• Fishing Rods: When your fishing rod breaks, SmartStack automatically equips another one, so you're always ready to keep fishing.

If you run out of items in the hotbar, they will be automatically refilled if you have more in your inventory.

This addon does not require any experimental toggle for its use. This addon will not stop working in future updates. If you have ideas of more features to implement to the addon, write them in the comments.
