      Code EditorComes pre-bundled with a SharedCode Editor (currently supportingJavascript, HTML & CSS) for tuitionsgeared towards teaching programminglanguages.


      Shared ContentThis plugin enabled one to sharecontent during the session, byuploading content in aPPT/Word/Excel/Image form andconverting it on the fly, to HTML5. Thecontent is then shared with all theparticipants, and as the presenterscrolls through the content the viewacross all the participants issynchronized, including the position ofhis/her mouse pointer.
