And you post answers a question I would never have asked, "I wonder if this will be useful to DrinkWater".

Different people's behaviour patterns and needs are different, not everything is useful to everyone so don't expect everything to be useful to you. It isn't something I'll ever use, but I can see why it might be a benefit to some (the author describes the intended utility pretty well).
