Multiselect for YouTube allowed me to backup and copy my writing playlist to another Gmail/YouTube account. I decided to do this after YouTube, out of nowhere, deleted my account due to a political video I had saved in my political playlist during the Biden and Trump campaigns of 2024. They said I violated YouTube terms by saving a YouTuber's video in my playlist. Apparently, this is something YouTube has done for a while, as I found multiple people online with the same complaints. I was able to get my YouTube account and playlists back in a few days. But to lose a 2000-video playlist of my favorite videos really showed me the need to have multiple accounts under different Gmails.
