Feature description

It would be great to have an absolutely positioned player with scrolling comments so the player stays fixed while browsing comments. This would be a major improvement to user experience.

Why do you want this feature?

The benefits of this are standalone, but browsing videos isn't the same without reading comments and vice versa. It's almost imperative to be able to do both at the same time!

Additional information

Just a thanks to the team for an already awesome project.
