As for rewinds, you can click on the progress bar to jump to a time you want. Also, the upcoming version of the player supports fast-forward/rewind/jump keyboard shortcuts: https://github.com/asciinema/asciinema-player/blob/next/src/...
As for the playback speed you can set speed, theme, font size etc (embedding docs say this - https://asciinema.org/docs/embedding), and you can append these options to any asciicast URL too, like this: https://asciinema.org/a/21743?speed=5&theme=solarized-dark
Looks like these are not easily discoverable from the player UI, so noting this down. Thanks for bringing this up!
Took about 10 tries of going back as far as the history would allow to get back here. I hate sites that do that junk.
