this still works, returning a feature that made no sense to remove. useful for moderation.

only complaint is i wish it was more clear that this only worked after switching to live chat in the dropdown! once you switch to live chat the option appears and then you can switch back to top chat and the option will persist.

the github link is dead when you click on/install the extension.

It worked! But only for "Live Chat / Replay" (not for "Top Chat"). And you have to hit "play" for the chat to load.
