Looking for a way to tell YouTube to ALWAYS load my videos in the nice expanded view (not fullscreen, but the one where it's the width of the page and actually visible on a decent sized monitor instead of this tiny thing).
^ Hitting the highlighted button will return your view to the small one.
I've found options to set what quality to try to view, I’m already set to the highest. I don't care if it starts @ 240p, as long as the viewport is wide. YouTube used to remember this setting when it first came out, but it doesn't now and I'm going crazy.
