I am looking for a program, user script, or web browser extension that can download all videos of a Twitch channel.
https://github.com/Franiac/TwitchLeecher is great to download 1 given video, but cannot download all videos of a Twitch channel (one would need to copypaste all the video URLs or IDs into TwitchLeecher).
Any license, price, web browser and operating system is fine.
