Hi, I think in cascade it would be a lot better if we could have a few things in some sort of interface in the preview screen.
The play/pause function, perhaps have a button like you do in the animation preview window.
Adjust speed etc from same place
have camera controls (ie, slow down camera) its too hard to use at times.
And perhaps have predefined camera viewpoints that you can switch to, or customise.
i think it would be nice to be able to step through a particle sim like that.
