Describe the feature you want

Ability to read comments while watching the video using the video player. You can currently achieve the same thing using popup player but it's inconvenient to change between them if you read comments often. Also there is a slight pause (and sometimes audio crack) when switching between the players.

Is your feature request related to a problem? Please describe it

There is no way to watch video using video player while reading comments.

Additional context

How will you/everyone benefit from this feature?

Depends on how you use youtube/NewPipe, but if you read a lot of comments and are familiar how it's done in youtube this is a great, and probably simple to add, feature.
