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.
• Locked slots:
  • Full-row swaps skip locked slots.
  • Single-slot swaps do not run for locked slots.
