The Upcoming Workflow Tasks pane lists upcoming workflow tasks. Scroll through the list to the end, where you can select View All Tasks, which takes you to the Home > Tasks page.
Select a task to open the Task Details dialog. The dialog contains details about the task type, status, priority, assignee, due date, and location. Depending on the task, you might be able to perform it directly from the dialog.
