[Request] Todo-lists to inherit the due-date of its todos

Images, notes, todo-lists and todos can have a due-date. Its possible to sort images, notes and todo-lists by their due-date. Most of the time (for me) the due-date of a todo is the relevant one but its not possible to find the todos that are eg. due today.

So it would be nice to see the next due-date of a todo at its list before opening the list - maybe in the title. And having this, the earliest due-date of a todo-list (either the explicit due-date of the list, or the next one of one of its todos - depending what is earlier) should be considered by the sorting.
