Describe the feature you want

It's really sad that Newpipe doesn't have the ability to access "Watch Later" playlist for shared videos. Having an ability to "Add to playlist" will make the experience much better.

Additional context

How will you/everyone benefit from this feature?

Watching later for any video will be possible. Plus, binge watching similar videos will be a breeze.

Sometimes, we need to browse several websites only to find different videos on the same topic. Definitely, having several queues on is not a good idea as the notification panel will get bombarded with too many media player notification bars which is not a good idea. Instead, after adding to playlist, we can watch similar videos later. This will also avoid accidental removal of videos from enqueued list. Plus, having too many enqueued lists is quite dangerous.
