A small QoL mod that makes offhand stack handling feel more natural.
If your offhand already contains a compatible item stack, the mod can refill it instead of immediately moving or swapping the stack elsewhere.
Shift-click refill
Shift-click a compatible stack in your inventory or a supported container to refill the existing offhand stack first.
- Offhand:
Bread x50 - Inventory:
Bread x20 - Shift-click
- Result: Offhand
Bread x64, InventoryBread x6
Smarter swap key
Pressing the swap-hands key (F by default) refills a compatible offhand stack before performing a normal swap. This works both during gameplay and while hovering an inventory slot.
Vanilla fallback
If refilling is not possible, Minecraft behaves normally. This includes:
- Different items
- Incompatible item components
- Full offhand stacks
- Non-stackable items
- Normal inventory clicks
- Hotbar number-key swaps
