It would be nice to have more control over the random action in the nodes.  A lot of particle effects could be accomplished easily if the Noise node had more flexibility.

1.  A control to make it denser or sparser.  This can be accomplished rather crudely with a Ceil or Floor math function, but direct would be better.

2. At present the randomizer is the same every time you render.  This is good when the Noise is used for grass or plaster that need to be the same in each frame, but it's not so good when the Noise is simulating dust or ions or other particles that need to move randomly.  Maybe an Animated switch like the green key thing on many other values.
