It's okay. If you need an extension to reverse the chronological order of playlists, this works fine, but there are REALLY stupid flaws. For example, the chronological options are REVERSED: sorting by "newest to oldest" actually gives you "oldest to newest" and vice versa.

Just needed a chronological order button for playlists, does exactly what I needed it to.

Does not work at all.

Re-order is now working with Watch Later list. It might have something to do with the fact that the option to reorder by date has been removed by Youtube

while it does reorder very neatly, afterwards the videos don't autoplay for me. I don't know if it's something on my end or (un)intended behaviour that's simply a part of it

I like the concept and that at least as far as I verified for now it's working as advertised.

I know its generally not the most appreciated thing when people ask for features but seriously an amazing expansion would be a simple button to reverse play list order.

Sadly other solutions that did that have been abandoned and this is the single most common issue with existing play lists that they are sorted from newst to oldest when logical watch order would want you to watch from oldest to newest.

Specially with larger play lists that would be a fantastic time saver over having to restack the play list 1 by 1 individually.

The quest to find something to help sort my unwieldy Watch Later playlist of almost 3,000 videos continues. No videos load when I try to sort that list, and there's some weird detection issue, because if I try to use it on another playlist, then it'll load the WL list, but only 200 videos. It's the start of a good idea, but it doesn't quite function as desired.

Dude. You did a great job. Just editing a sick playlist by dragging and dropping is not cool. You can just make a text list. And add a reverse button. Normal users usually need to view a large playlist from the end. Too bad I'm too dumb to fork with this button.
