I was sure I would see this here, as I discussed it with another user (who I can't remember, else I'd give credit) in global chat, but we need an indicator somewhere for showing how many favor points we've got with all the Giants in a particular day. I understand that we can max those out, just like energy from meditation or coins collected in a day.
I'm thinking an indicator for each Giant in the header bar between the learning rock and the 3 icons on the right for bug reporting/sound/I can't remember the third one. Maybe something in the shape of each shrine that shows the favor points by day as a mouseover?
