Completed tasks in web app#4334

When I have a lot of tasks in a day (which I do, because I like small tasks) when I’m halfway done and half of the fifty tasks in the list are done, finding what needs to be done next becomes challenging. I’d like the option of hiding completed tasks, moving them to the bottom of the list, or moving them to another list so all of the options that are open to do now are in one place and not mixed with everything I’ve alread done.
