I'd really like some placeable bubbling water/steam vents, for recreating more volcanic looking parks.
I think it could be implemented by locking down a surrounding area of water, like the fish feeders do, and perhaps give it boundaries so that dinosaurs don't walk right up to it (so, a small steam vent in the middle of a square area dinosaurs don't walk in).
I'd also like a more obvious Mud brush, as the current Dirt brush is pretty subtle.
