Problems with thumbnails I come to report that several videos have thumbnails that look corrupted, perhaps it would be good if you tried to solve this problem.

Website Layout changing the website layout

Autoplay Option in Playlists An autoplay option in playlists that allows the user to automatically go to the next video in a playlist would be very useful.

Report comment functionility The ability to report comments needs to be in place, especially in the most toxic comment sections...

Audio Videos Instead of having to upload a video with music, why not just allow the user to upload a sound file (like an mp3) and a title image to go with it? It would allow for much higher quality music videos and they might be smaller too.
