The edX video player was recently updated to make options for downloading videos, transcripts and handouts more accessible, as shown in the illustration above.
All of the extra features are explained in detail by Open edX Learner’s guide page.
Additionally, in “Discussions”, the list of topics and the controls available for adding a new post have been updated. The Topic Area list now defaults to the “General” topic if there is a course-wide topic named “General”. More info is presented here.
