Would like to see more 3d water props to apply when you need water at more than 1 level.

Also would love to see more special effects / particle packs.

I agree with razr on the water bit. It is useful for stage business to be able to pour a glass of liquid from a jug. i can see how to get water in the glass and water in the jug. Harder to get the pouring water and the splash as it enters the glass.
There was a video from a pro outfit a few years back - but no explanation as to how it was done.
