YouTube Dynamic Web Fullscreen 作者： DYNAMIC BLINK

Maximize your viewing experience on YouTube with a single click.

YouTube Dynamic Web Fullscreen allows you to force the video player to fill the entire browser window without entering the traditional full-screen mode. This is perfect for multitasking with "picture-in-picture" style viewing or maximizing screen real estate on ultra-wide monitors.

Key Features:
* True Window Fill: The video resizes to fit your browser window exactly (100% width and height).
* Aspect Ratio Safe: Automatically adds black bars (letterboxing) so the video never stretches or distorts.
* Distraction Free: Instantly hides the comments, sidebar, title, and top gradient for a clean, cinema-like view.
* Smart "Always-On-Top": Uses advanced layering to ensure the video stays above all other YouTube elements.
* Zero Data Collection: This extension runs locally and collects absolutely no user data.

How to use:
1. Open any YouTube video.
2. Click the extension icon.
3. The video will expand to fill the window.
4. Click again to return to normal view.
