Hello

First off, thank you for the hard work for this feature.

I have the new build and stable build side by side

1. I perform the search from the main playlist tab and wasn't able to find my videos in the default playlist that was created. It was being search just fine at the stable build.
2. If possible also search option when inside the playlist.
3. If also possible a sort option inside the playlist, so that the last item in the playlist would show up first. Would be helpful once starting the migration to the new playlist.
4. the current button in add to playlist which you can copy the video into the new playlist, if possible could the move to the new playlist be added as well so that we don't have to delete the video after copying.

Just fixed a bug found when I use the build myself: playlist link in watch page not having playlistType

I did a search in code and there should be no other places having link to a local user playlist

The "Remove Watched Videos" button is displayed inside of playlists, even when "Remember History" is disabled, is that intentional?

I think it is, disabling that feature applies only on future watched videos not previously watched videos

Wow, finally. Never though I would see this get merged in my life. Thanks for the work @PikachuEXE!
