Make completed tasks temporarily visible at the end of the list
I like to do-lists for two reasons. First they help me organize stuff. Second, they show me how far I've already gotten. Wunderlist is great for the first point, but not for the second. As soon as I complete a task it disappears on the list and the warm psychological feeling of completing a task disappears as well.
Therefore, I would like to optionally be able to see completed tasks at the end of the list for a to be specified period of time (e..g, 1 hour, 1 day, 1 week, 1 month). After that period, the task can go to the list of completed tasks or wherever. This would also allow me to monitor tasks completed by others more easily.
Additionally, it would be nice to see directly who completed a task in a shared list, but that's a second request, I guess.

I agree and I would love to have this feature back. I think seeing items checked off is invaluable and a minimal function for a todo list to do its job. Checked items also help those of us who are forgetful and need to keep track of completed todos, it's a basic requirement for alot of people that use your app. Thanks.
