"Enlarge the theatre-mode youtube video"
A small script that enlarges the YouTube player size (height) so that is covers all the page, rather than showing text below like video title. Great for watching the video in theatre mode without using full screen, while still utilising the maximum space of your screen.
I don't expect it to be robust, nor has it been tested across multiple screens. However, it shows which is the html element and the style required to make the change. You can adjust the "96vh" to be larger if it is not taking up enough space, or larger to cover even more height. And adjust the time (2000 milliseconds) if it is not having an affect even if tapermonkey says the script is loading, which might occur if youtube is still loading the page fully before the script runs.
