Description

This online tool at https://ytmdl.deepjyoti30.dev/ does not support downloading playlists (from youtube).

It would be really useful if we could download music playlists.

@aha999 That's an issue for the webapp which is also opensource at [https://github.com/deepjyoti30/ytmdl-web-v2] and there is already a feature request for that.

Please continue the conversation over #18
