You should be alerted when your keys or gunshots/chips have regenerated or are at max capacity. Thats the whole reason for push notifications is so you dont waste time. Not everyone can remember to use their keys every 30-45 minutes and need a reminder or use their gunshots every few hours. Just a suggestion.
I can see how this would be useful to some, but I have gotten so used to having to check for keys every time I log in so that they keep regenerating, this wouldn't do me any good.
You should also add push notifications for when your stamp or energy is full. It would be best if it were an option.
