I wish the watch app displayed the time while I'm shopping. That's a pretty basic major oversight. On the phone app, when I try to scroll through my list it interprets any touch of the screen as a tap to add that item. It drives me nuts. I have to constantly delete items I didn't add that I just touched by tapping to scroll. If I tap and linger just a moment too long it interprets it as a long tap and adds 3 or 4 quantity of whatever I tapped.
