for http://popoutmaker.mitsunee.com/youtube/ the default options are all off, but for example http://popoutmaker.mitsunee.com/youtube/https://youtube.com/watch?v=G70-EYAhF9M the defaults are on,on,off which is the expected outcome.
Furthermore the link http://popoutmaker.mitsunee.com/youtube/i does not work, which is supposed to simply disable annotations.
Streamer could then set up a button in the description that links to a popout with their settings (example: native stream resolution instead of twitch's page having 755p even for 720p streams)
