It would be really great if we could have a download option for the videos in the codeforces EDU section courses.
Since, it would help us to download the videos when we have unlimited internet access and watch it whenever possible.
Or else we could have a official codeforces youtube channel, since youtube allows to download and watch later without internet, and also a youtube channel could generate some revenues for codeforces.
MikeMirzayanov please look if you could do something.
