At the top of most screen you will find an input filed. Adding a new task is as simple as typing in this field and taping the "Add Task" button to the right. Your new task will be added to your list.
It's important to know that new tasks created are "location aware" and when adding a new task in some view modes, the task will be added directly to that view and not to the inbox. For example, adding a new task while in the NEXT screen will add the new task to the NEXT list and not to the inbox. This is helpful when adding several tasks quickly but you don't want to spend the time filing them away. To help minimize confusion, the input field's placeholder text will tell you where the task is being added.
