I've noticed recently that the modal which appears at the end of a video and counts down to when it will auto-advance appears broken. Both input options cause the site to advance to the next video, which I assume is not intentional. I wasn't sure where else to submit the bug, so I figured I'd post it here.
As long as we're on the topic of the player, I think it'd be really nice if the system could remember that it was in full-screen and play subsequent videos in full-screen as well, or maybe just a toggle for this in user settings. I have no idea if browsers would even allow this, but a guy can dream.
I doubt this is relevant, but I'm running Chrome on a MacBook OS X 10.12.6. Thanks for all the great work you do for us, Jeffrey!
