Finally found a way to window YouTube TV to watch split screen on an ultrawide. This is a huge improvement over a snapped window browser.

I have a collapsible tab bar, so enabling windowed full screen will fill up the entire program window, which I can then place wherever I wish. It's perfect, and wouldn't be possible without this add on.

Very useful addon. It allows you to repurpose the websites fullscreen modes to get more information on your screen at all times.

The developer has also been very helpful in fixing bugs and adding support for new kinds of websites. Highly recommended.
