I was just wondering if you could add youtube videos to novels? Does it just show up as a link or is the embedded video thumb able to be seen and played?
Are you talking about in the description or the novel itself? Well, short answer is no, it doesn't show up as a link in the novel either. It's a link in the description though.
At present no I don't think there's a video embed option for novels, or comics for that matter. So for you can add images and gifs but not much more than that.
