The To-Do App is an application that manages tasks a user has to do. Each task has a title, a description, and a date of completion. Each task can also be associated with several notes. When a user enters the application, the main screen is displayed. It presents all the users tasks. Then, the user should be able to manage the tasks: create new tasks, view and edit the details of an existing task or instead delete it from the list. The information of every task should be stored persistently. Consider the use case Add a Note to a Task: Use a Sequence Diagram to model the interaction in the basic flow.
