重複してたプレイリストの動画がが楽に削除できた。ありがとう！

I wish youtube developers put at least half the effort into their UX as what this plugin authors did.

Straightforward enough! This cleaned up a playlist I curate that just today had about 260 duplicates added for a total of 1100 items. Took a while, but once it started working properly, the process was seamless and kinda fun to watch too! Saved me days of fiddling. Thanks!
