Task is the classic Trello card with an optional image, a title and a set of icons
List is composed by a title, a list view of Tasks and a button to add new tasks. Every task is clickable and on the click a popup appears. This popup contains informations about the task. From here you can update title and image path of the task. Besides you can delete a task. Another popup is available when you click on the "add a card..." button, with this popup you are able to create new task, setting the title and an optional image.
In the main we have the board, it has to be a ListView of Lists. I am struggling with it.
