Hey I agree with the above. First off your app is almost perfect! However to me the lack of said functionality drastically reduces wunderlists practicality and motivational application. Project managers, psychologists, people involve in personal development would all agree. Being able to see completed tasks and subtasks has both practical and motivational applications. I'd recommend it as an option that can be applied our not at the will of the user. I believe this feature with its added applicability would attract more users and increase your market share. Kind regards.
