I would like the yellow-highlighting feature turned on by default. (rather than the current behavior where a user has to click the button to turn it on) Still, we can keep the button and let a user turn it off if they don't like it.
Currently, when a growth turn happens, all the volcanoes are highlighted. Now that dormant volcanoes have been introduced, I would like to not highlight level-four volcanoes that didn't grow (e.g. they're dormant).
