I only tested on Chrome on Windows. To use (you'll need to install Tampermonkey for Chrome or Greasemonkey for Firefox, first):
- Install the script (link).
- Go to the F1TV video you want to watch, as normal.
- At the bottom right of the player there is now a new button that is just the outline of a rectangle.
- Press that button to toggle between large and default size.
That's it. Feel free to report issues on issue page or make PR fixes.
