D5 scatter tools are very impressive, but feel a bit clunky. Here are my suggestions:
1: Add a scatter zone. Like scatter path, but instead of a line, we can create a zone, where objects are scattered inside this zone, with something like a falloff setting that slowly decrease density and or size at the edges
2: Add settings that lets us choose the ratio of different scattered objects. ex:
Object1 = 0.8
Object2 = 0.3
Object3 = 1
3: Let us choose any object, not just vegetation.
4: And of course, increase the 6 objects limit.
