For example, video quality (high , med, low), interval of some on/off options(1 min, 3 min, 5 min, off),
when these go to a vertical menu. How do we determine the order of them? descending from top to below? I think we are used to seeing options like video quality having the best quality at the top, worst at the bottom. How about quantities? I think I've seen both cases somewhere, but I think there should be some theories/norms behind, yeh?
