How do I view and filter tasks?

Go to Tasks --> Options 

Scroll down until you see the "Update" tab, and click on "Planner" as shown below:

Now, you will see the Planner menu. You will be able to filter tasks by both user and status. For example, I have set the status to "open" and a list of tasks appear. You can also change the schedule timings, from day, to week or month, by clicking on the time frames on the right.

If needed, you can also create a task by clicking "create task" on the right.
