Objective: Introduce a native, fully interactive, customizable full-screen chat overlay to enhance the Twitch user experience.

Current Issue: Third-party extensions for full-screen chat are not universally adopted, which leads streamers to embed chat in their broadcasts, detracting from the full-screen content experience.

Proposed Feature:

A native, interactive full-screen chat overlay, adjustable for transparency and screen positioning.
The ability for viewers to toggle the chat overlay on/off based on personal viewing preferences.

Key Advantages:

Delivers a seamless full-screen experience with interactive chat, a core part of Twitch's live-streaming.
Unifies the viewer experience across all streams, ensuring everyone can use the chat feature without additional extensions.
Improves content quality, especially for clips, by keeping the main content unobstructed while still engaging with the community.

Rationale: A native solution is essential to provide a consistent, inclusive, and immersive full-screen viewing experience for all Twitch users, which current extensions cannot fully deliver.
