This is a feature extracted from the updated Scroll Volume DX version: https://greasyfork.org/zh-TW/scripts/536402
Functionality is limited to replacing full-screen YouTube views with either: 2. Browser API, or 3. Maximized webpage (including interface), or 4. Variation (no interface, only video pinned).
The default is 2. Browser API, where double-clicking and NumpadEnter trigger the maximize switch; 4. Because there's no interface, a single click pauses the video.
The original version excluded mode 4 because it couldn't be implemented.
