✋ Shift2Offhand

A tiny Quality-of-Life Minecraft mod that lets you shift crafted items directly into your offhand.

Minecraft normally prevents shift-clicking crafted items into the offhand when your inventory is full — even if the offhand already contains the same item.
Shift2Offhand fixes this small but annoying limitation.

✨ Features

• 📦 Shift-click crafted items into your offhand
• 🧰 Works even when your inventory is completely full
• 🔄 Automatically merges crafted items with the stack in your offhand
• 🎯 Only activates when it actually makes sense

⚙️ How It Works

This behavior only triggers if the same item is already in your offhand.

Example

1. Your offhand contains 10 Oak Planks
2. Your inventory is completely full
3. You craft Oak Planks from logs
4. You shift-click the crafting result

➡ The crafted planks will merge directly into the offhand stack.

📉 Stack Overflow Behavior

If the crafted items exceed the maximum stack size:

• The offhand stack will fill up to 64 items
• Any remaining items will be dropped on the ground

This ensures:

• ❌ No item loss
• ❌ No blocked crafting
• ✔ Consistent Minecraft behavior

---

🎯 Scope

Shift2Offhand intentionally keeps things simple and lightweight:

• ✔ Only affects shift-clicking from the player's 2×2 crafting grid
• ✔ Does not modify normal inventory mechanics
• ✔ Minimal performance impact

💡 Why This Mod?

Because if the item is already in your offhand, Minecraft should simply stack it there — even when your inventory is full.

Small fix. Big convenience.
