Automatic Potion Restocker

Automatic Potion Restocker is a client-side Fabric mod for Minecraft 1.21.x that keeps your hotbar stocked with potions during combat.
The moment you finish drinking or throwing a potion, the mod uses legitimate inventory actions to:
- Drop the empty bottle (for drinkable potions), and pull the next matching potion—identical bottle or same effect set from your inventory back into the same hotbar slot (See Video at the bottom) .
- It supports drink, splash, and lingering potions, so you never have to open your inventory mid-fight.

Features
- Automatic restocking after using a potion
- Works with all potion types such as drinkable, splash, and lingering potions
- All actions go through normal inventory packets, so the mod behaves like a real player and remains compatible with vanilla and most other servers.

HUD Overlay
- A lightweight HUD in the bottom-left corner shows how many potions of each type you still have.
- Toggle HUD visibility with P.
- Hold Tab to reveal effect names and duration of the potions next to each icon for quick reference.
- The HUD is minimal and designed not to clutter your screen during combat.

Configuration
- The mod integrates with Mod Menu and provides a simple configuration screen:
- Enable or disable the automation entirely.
- Toggle the HUD overlay with P (changeable in MC settings).
- Change the Position (via Offset).
- Change the opacity
- Choose the HUD text color via presets colors or ARGB HEX Codes.

Compatibility
- Client-side only
- Works on any vanilla or most other servers
- Uses only normal inventory actions, making it broadly compatible with other client-side mods
