Hi, this is not related to Deep Learning in any way. I just want to point out the default playback screen on fast.ai is very unrealistic as the video window is very small and would definitely need to play it as full screen. On the other hand if the video page can be tweaked like this below, then it would have been much better. Its entirely my opinion so please share what you think.
If the video player can be edited to full width and the description text below it. It would be much better UX experience i think.
