Suggestion: Add support for navigation UI in fullscreen, if I am not mistaken Safari lacks support for navigation UI while in fullscreen, this makes the YouTube experience more boring while in fullscreen, how? Well see when navigation UI is enabled on say Youtube it allows you to scroll down while in full screen to see comments and suggested videos without leaving full screen, Firefox and chromium have this but not Safari, it is honestly not a requirement but I would love this functionality 😁
