I updated the fork overnight, so now you can download your Google Takeout data as a ZIP, import it, wait about 5 minutes, and voila - all your playlists are available locally. You can add to them locally, obviously, but those changes won’t sync back to YouTube. “Likes” and “Comments” obviously don’t work either.
Sorry, I couldn’t figure out how to do local avatars or progress indicator bar for the import (well, I mean, I could…I just couldn’t be arsed to spend another 4-5hrs doing it, then testing it etc etc).
Enjoy your pirate youtubez, yarr!
EDIT: I’m going to see if I can figure out a way to import subscriptions as well. I think the “easiest” (meaning, least work for me) pathway is to do Google Takeout—>import the ZIP into pipepipe or newpipe (as it has the machinery in place)–>export the cleaned JSON—>Import that into Smarttube LOCAL.
Less things to break doing it this way.
No, sorry it does not (unless they changed something upstream in 35.52 that allows for that).
This is simply to bypass having to log in in the first place / sync your playlists offline…but if the video is youtube restricted / needs OAuth, then this doesn’t bypass it.
