YouTube is such a horribly designed site. The best feature they've added in ages is the queue option, bet even that is busted as hell. Half the time an "add to queue" button appears on the thumbnail of the video, but the other half of the time it doesn't and you have to click the ellipsis menu. Even when you can click the button, it will select element of the page which leaves the video auto playing unless you hover back over it to stop. The queue itself disappears if you close and re-open the tab which is plain annoying. The video player itself sometimes breaks and requires me to reload the page. Ambient mode is annoying and I dislike it being on by default. Sometimes I click on a thumbnail but it has an on-hover action that spawn a link to their "about sponsored content" page right over the thumbnail where I wanted to click on the video, then when I hit the back button the home page has refreshed and the video I wanted to watch is gone.
