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.
