Hotbar Switch

Hotbar Switch
Your whole inventory, one keypress away.

Minecraft only lets you use your 9 hotbar slots while you play — the other 27 just sit in your bag. Hotbar Switch lets you instantly change which inventory row is in your hands. Tap a key, the arrow keys, or scroll, and a different row slides into your hotbar. It's like carrying four hotbars at once.

✨ Features
⬆️⬇️ Switch rows in a tap — Up / Down arrows, R to cycle, or hold Left Alt + scroll.
👀 Live preview — a small panel in the top-right shows all your rows with item counts, and a green highlight slides to the row you pick.
🎒 Works in the inventory screen too — reorganize and switch at the same time.
🔊 Tactile feedback — a soft click on every switch.
⚙️ Fully rebindable in Options → Controls → Hotbar Switch.
🌐 Works on ANY server — nothing to install server-side
In Minecraft the server controls your inventory, so a client-only mod can't add real new slots. Hotbar Switch instead rearranges the 36 slots you already have, using the exact action the game performs when you press a number key over a slot — so the server validates every move:

✅ Works on vanilla, public, and modded servers — and singleplayer
✅ No server mod required
✅ No item loss, no "ghost" items, no desync
🎮 Controls
Control Action
↑ / ↓ Move the selected row up / down
R Cycle through all rows
Hold Left Alt + Scroll Move up / down between rows
Normal scrolling still selects your hotbar slot — rows only switch while you hold the modifier key.

❓ FAQ
Does this add more inventory slots? No — nothing client-side can on a server you don't control. It gives fast access to the slots you already have.
Can items get lost or duplicated? No. Every move is a normal, server-approved swap.
Does it work on servers? Yes — any server. It's 100% client-side.
