When exiting daily tasks in mid stream for any reason, I have to recategorize the entire list from the beginning. When the list is long, this is a lot of work. Can you make it save, perhaps intraday, and add a back button to each item for re-review if needed? When my list is very long, this is a lot of work. Makes me not want to mess with it and I don't think that jibes with your mission statement.
