Suggestion: Display Settings
I’d very much like for some particular screen notifications to disappear. For example, when you take a speed boost in various cities, it displays a pop-up you have to click to get rid of it. Just give us the speed boost and don’t tell us about it.
Same with anvils – they have one job. Just do it and don’t force us to go through a dialog. We can see the damage indicator below our HP indicator, and we can see it disappear after using an anvil. No need for a dialog.
