The way this app goes about deleting items confuses me. Why can't I delete completed items and why can't I delete more than one item at a time? If I'm making a list whose history I don't need to save, like a grocery list, I don't want to have to go back when I'm done, un-check each item individually, and then delete them one at a time. It's a fantastic app otherwise but that makes it really high maintenance. Maybe that's not what it's intended for.
