This just gave me an idea that I don't think I've seen suggested before. Instead of trying to fit the reset button onto the main screen, which I believe was deemed problematic in the past (for space reasons), how about adding it to the info panel mentioned here?
It would fit nicely next to the Rewards box, under the See All Objectives button. It would be out of the way, reducing the chance of accidentally clicking it. But it would still be way more convenient than it is now. What do you think of that idea?
Oh, that would be a neat way to deal with it. We'll keep it in mind.
