When you are adding videos to your playlists Sometimes you don't remember if you've already added that video. This script puts an H button next to the search bar to Hide videos you've already added to your playlists, so there are no duplicate videos in your playlists.
Hello,
It's possible that the YouTube homepage is automatically loaded without the videos from the playlists and without the big holes that appear when you press the H button please ?
Thank you for your answer.
