Player Highlighter

A lightweight client-side Fabric mod that highlights players with a glowing outline while the player list is visible, without relying on any server-side mechanics.

Overview

Player Outline Highlighter improves player visibility by showing a glowing outline around players only when the player list menu is displayed.
The effect is temporary, purely visual, and handled entirely on the client.

Once the player list menu is closed, all outlines disappear immediately.
