You can now press the w key to toggle the script, though it might be changing to another key now that YouTube is using it.

Love this script, been using it for years. Only addition I would love is a way to change back to non-theater mode without completely disabling the script. Currently you can't use the chat while watching a youtube live stream because the chat is stuck below the video.
