Suggestion on playlists and general usability

[DanDanG1224]

I think it would be great if you could download all the songs from a playlist and not have to download them all individually. That would make the app much more streamlined. Another thing you could add would be if you press and hold on a video you can download it. I think these would make NewPipe way better, but thanks for all you've done so far!
