If your collaborations include team projects, it can be incredibly helpful to incorporate applications such as Trello (http://www.trello.com) and Slack (http://www.slack.com), since it is possible to assign roles, milestones, charts, and to attach drafts, all within the Moodle framework.
Another useful productivity tool is Evernote, which you can also sync with all your devices so that it is a tool always at your side; it is useful for jotting down ideas, assignments, and notes. Other productivity tools include Google Voice, which allows you to use speech to text and to create instant transcripts.
