Buildable Location Toggle

[Ranec1]

(Easier) Idea #1 - Change the color from red boxes to yellow or something when it is rough ice that can be melted. This would at least indicate the item could go there if melted.

Idea #2 - A map/keyboard toggle that shows the locations that can/cannot be built. This would make it obvious when something cannot be placed in an area.

Mostly on Aquilo, but also Gleba, it is very difficult to see where one is able to build. There is rough ice that needs to be melted first then there is smooth ice which cannot be built on at all. I constantly have to melt an area then see if I can build where I want.
