Installed the extention, it worked for a first 3 times then extention's blue button near a notification bell disappeared to never be seen again when I was in the middle of rearranging my playlists. So its useless right now. Thankfully I've got backup of my playlists but the damage has been done.

Edit: now the button appeared, but I can't import videos from an exported backup list I've done in the previous version, no matter whether its JSON or TXT format. Pasting copied videos from extention memory does not seem to work either. On all my efforts it responds with only "precondition check failed" error message.

UPD: It appears that Precondition check fail error was due to playlist having removed/private videos, so selecting these videos for copying or moving into another playlist results in failure. Other than that extention works fine.

UTC 2024/10/02 19:28 was just updated, never thought it would again since it was dormant since dec 2023.
guess I'm donating

correction. import only works for Watch Later not custom lists. UTC 2024/9/29 15:27

Well seems like it got fixed by YT 2-3 hours after writing the below. fixed as of UTC 20:39 2024/9/28

~~importing videos stopped working. This could get resolved by Youtube on its own in the 40th week (I'm writing this in week 39, 1 day before week 40) because this addon hasn't been updated since Dec 2023 and this happened already once, so it might resolve on its own.

In the meantime, for Chromium only, to import, resort to 'Playlist Importer For YouTube'. This gives you 10 video per import. (It opens the videos and adds them to playlist).
If Youtube is so smart as to break that function, have fun with your servers getting saturated for no f' reason.

for now it's 1 star for the meta. I will change it.~~

The most useful feature is not implemented:
- "select multiple videos & move them to position n"

Only available is:
- move to top
- move to bottom

Well then i can also just use the youtube UI which is similar unhelpful
