Calendar view on the All Tasks list is the superior way to look at your tasks for the day, in my experience. But, what would make it even better is being able to create a calendar event, not just a task, with the same click/click-drag function as creating a task on the calendar view.
Currently, you can only create the tasks on the calendar view, and create events in the planner. So you have to go back and forth when planning out your day. Would be awesome if you could do planner events from within the calendar view, or vice-versa; simply click/drag like you normally do, and be able to specify if you are making a task or an event.
You also have the Create Task button on the top left where you can also create a different type, like a milestone or custom task type from the workspace, and having an event option would be awesome.
