So why is the button to go up below the button to go down?
I'm used to it now but the "Advance" and "Quit Expedition" buttons are still dangerously close to one another.
Seems like a UI overlook and flaw to me.
I'd vote "Quit Expedition" to be at the top in-line with the heat meter but centered. That way you'd have to be pretty clumsy to press the wrong one.
I once almost quit a shadow lair expedition due to this. If my mouse had been just a tiny pixel off I would have lost 1,800 energy with little reward and be forced to leave my party members to fend for themselves. Ever since I've always had to take a second or two to make sure my mouse was firmly placed over the "advance" button before actually advancing.
