Downloading should be easier
Currently I can download all the videos of a course using iTunes or using the link below the video.
iTunes is a mess. Classes appear out of order or do not appear at all. Some courses are not there.
Downloading one audio/video file at a time is tiring. There should be an option to download all files from a course with just one click. You could even use BitTorrent.
Downloading all audio files at once to create an audio course is an easy win.
PS. Downloading the video could also include the option of .SRT files for subtitles/captions.
