Everything works beautifully right now except my favourite, absolute life-saver feature - peek audio transcription. The userscript version is returning "Uncaught TypeError: can't access property "style", transcriptTextContainer.firstElementChild is null" in console, so I switched to the firefox extension and that's doing the same thing with "TypeError: Node.appendChild: Argument 1 is not an object". The peek window shows up with language options, but the field where the transcript would appear is empty. Tried the ms edge version just to make sure it's not firefox, got the same result.
Maybe Youtube broke something?

No longer working. Please fix this.

Great addon thankyou!
Can you please add ability to zoom in "Peek video content" something like Ctrl + mouse scroll button

Good idea. Everything works except "peek video content" option. It only gives me a pop-up saying that "Storyboard not available for this video!"
Tried for different videos with different posting times and views. Its all the same. Nothing has changed

Very useful addon, saves a lot of time, works very well.
You can also translate the transcript and copy it to another programme like notepad.
