Managing To Do's on an Android device
You can create, edit, and work with To Do's on your Android device.
To work with To Do's, press the To Do application icon on your device screen.
Note: The server implementation of To Do categories requires every
category to contain at least one To Do. However, there is no such
requirement on the client. As a result, To Do categories created on
the client are not synced to the server if there are no To Do's under
that category.
