Adds time information (duration, currentTime, etc.), adjusts for playback speed, highlights the active speed button, toggle for hiding/showing the control panel, and font size control.
This adds a persistent vertical control bar to the right of the screen which lets you quickly adjust the speed of any audio element on the page. I built it for manning.com audio books, but it works with ChatGPT audio as well. Likely it works elsewhere too. But, I advise you to change the "match" setting to limit it to where you want it to run. It shows helpful info like the original duration, the adjusted duration, how much time remains at the current playback rate, etc.
I've tested it with Firefox on a Samsung tablet. That's what matters most to me, your mileage may vary!
