I've come to terms with the fact that Google, probably intentionally leaves certain things for the developers to implement themselves. It's not like they haven't thought of the option or even debated on making those options toggle-able. It's perhaps best to just lay the infrastructure down and let the city build itself.
And my own thoughts about the percentage only showing lower than 50%. Amazing, IMO. I use the two finger swipe to check percentage but only below 50 is when I really need to know where my juice is at if I'm going to be away from the charger.
