Suggestion: Colored pools of water/lava

I am loving this game, but at that point where I want more variety for the zones.
I would love to be able to do a Fel Zone filled with glowing green pools and black rock mountains. I would also like to do a lava zone.
If we could get a tool tip for laying down colored “water”, green, blue, red, etc that would be nice.
Some 3d items letting us build ruins would also be nice, crushed pillars and crumbled buildings etc.
