A system comprises client devices that include user interfaces that comprise workspaces that can be used to display a live history of a multimedia collaboration session. The workspaces can be private and can be configured to display information representative of media elements that can be shared within the multimedia collaboration session, but that are only viewable to a participant associated with a particular client device. The private workspaces can be used to preview information before publishing it to other participants or to view a live history of the multimedia collaboration session.
