SlotGlow
SlotGlow is a client-side Fabric mod that replaces Minecraft’s default hotbar selector with a clean, customizable glowing highlight.

Configuration
SlotGlow is configured through Mod Menu.
To change the settings, open Minecraft and go to:
Mods → SlotGlow → Configure
From there, you can customize the color, glow, rainbow mode, pulse speed, size, opacity, outline style, and more.
Requirements
- Fabric Loader
- Fabric API
- Mod Menu

Compatibility
SlotGlow is client-side only, so it does not add blocks, items, mobs, or gameplay changes. It only changes how your hotbar looks on your screen.
