About this Mod
✨ Fast Pots Features
Select which hotbar slots – Choose exactly which slots (1‑9) should receive potions. Customize it to your playstyle.
Filter by potion type – Pick between healing potions, buffs (Speed, Fire Resistance, Regeneration, Strength), or both. Only the potions you want will be moved.
Auto‑replace items – If a configured hotbar slot contains a non‑potion item, Fast Pots can automatically replace it with a potion from your inventory (optional, toggleable).
Simple activation – Just hold Shift and hover over any potion in your inventory. It will instantly move to the next available hotbar slot you've selected.
Adjustable delay – Set a delay between moves (10‑100 ms) to prevent accidental rapid transfers.
Visual configuration screen – Uses Minecraft's native textures to display a grid of your hotbar and inventory. Click or drag to select slots and tweak the delay – all with a clean, intuitive interface.
Persistent config – Your settings are saved in a JSON file and reloaded automatically.

⚠️ Disclaimer
This mod is client-side only and does not modify game files or network packets. However, some servers may consider automated inventory management (such as quick potion moving) as an unfair advantage and therefore forbidden by their rules.
Use this mod at your own risk. I am not responsible for any bans or other sanctions applied by server administrators. Always check the rules of the servers you play on before using any client-side modifications.
