NewPipe has a one-click download button. If one follows channels with mainly-audio content that one may want to listen to later, possibly away from an internet connection, that is super-handy.
NewPipe also lets you export your subscriptions (which is just a bunch of links to RSS feeds), so you aren't shackled to Android/RSS.
Also newpipe let you create a playlist of videos and only play the audio track in the background or play a given video in the background
Can I somehow import my current subscriptions from Google into newpipe? When I tried newpipe what put me off was that I already had a list on the browser. I also couldn't sync the list between multiple devices. Also is there anything on Linux I can use to sync to newpipe and resume videos on my laptop if I'm tired of watching on my phone? Of if I saw something interest and I wanted to continue on Linux in order to take notes and make proofs of concept.
