Viewing and creating activities in the Planner

All scheduled tasks will show up in the task list below. If you filter for Completion=Unchecked you'll only see those activities that you have not completed.
On the right hand side you can select which colleagues' calendars you want to view.
There is a small triangle that can be used to maximize the calendar view. This will hide the Settings menu on the right. If you hide Settings you can reveal it again by clicking the small triangle again.
