About this Mod
🖐️ Offhand In HUD
Bring your offhand slot everywhere.
No more opening your inventory just to swap a torch, Totem, food, shield, or end crystal ⚡
Offhand In HUD adds a fully interactive offhand slot directly into container GUIs — chests, barrels, shulker boxes, modded inventories, and basically any screen extending AbstractContainerScreen.
The slot behaves like a real vanilla slot, supports full mouse interaction, and blends seamlessly into Minecraft’s UI as if Mojang added it themselves.
