This is a chat-based add-on that fully complies with Blizzard's add-on policy.

Intelligent PI Detection: Automatically recognizes Power Infusion requests in multiple languages (English: "PI", Korean: "마주", Chinese: "注入") and displays them in a sleek, centered UI.
Class-Colored Name Display: Instantly identifies the requester's class and displays their name in its unique class color (e.g., Light Blue for Mages, Purple for Warlocks) for faster targeting.
5-Level Sound Amplification: Features a powerful sound-stacking system that allows you to adjust the alert volume from levels 1 to 5, ensuring you never miss a request during loud raids.
Customizable Auto-Hide Timer: Includes a smart slider to set an auto-hide duration (1–30 seconds), keeping your screen clutter-free even if you don't have time to whisper back.
Lightweight Drag-and-Drop UI: Use the /piam or /마주 commands to easily reposition and lock the alert frame anywhere on your screen with minimal impact on system performance.
Note on Direct Rendering Mode: To bypass Blizzard's in-combat restrictions, this addon uses Direct Rendering Mode during boss encounters. As a result, it cannot filter specific words in combat, meaning ANY incoming whisper will trigger the PI alert, not just the word "PI".
