Extra Hotbar

Fabric client mod that adds dual-hotbar swapping utilities and compact HUD info overlays.

Features

• Dual hotbar swap system:
  • Swaps between your visible hotbar and a configurable secondary inventory row.
  • Supports full-row swap and single-slot swap logic.
  • Hold and tap swap behavior:
    • Tap or hold the swap key for different actions (configurable).
  • Per-slot double-tap swap:
    • Double-tap number keys 1-9 to swap only that slot.
  • Slot lock support:
    • Lock specific hotbar slots to prevent them from being swapped.
  • Active bar indicator:
    • Shows whether primary or secondary bar is currently active.
  • Panel cycle mode:
    • Cycle HUD info display through: Off -> Armor -> Food -> Both.
  • Armor panel info:
    • Shows equipped armor pieces and remaining durability.
  • Food panel info:
    • Lists edible items currently in inventory with hunger and saturation.
  • Persistent client config:
    • Settings are saved and reloaded from JSON config.

Controls (Default Keybinds)

• R: Swap hotbars.
• H: Cycle HUD panels (Off -> Armor -> Food -> Both).
• K: Toggle lock on the currently selected hotbar slot.
• 1-9 double-tap: Swap a single corresponding hotbar slot.

You can rebind these in Minecraft controls.

In-Game Behavior

• Spectator mode: swapping logic is skipped.
