Thanks Ondra, I didn't know. But I, and I think 80% of Corona Users, doens't know how to do this.
So, for the commercial version, I think you should create a Macro not only for this two important tools.
But, also, for to create a lights (sun and lights), fractal, scatter, proxy, Corona listener, converter, Autofocus, etc... and, create a real Corona Toolbar, with icons.
It will be more "professional". I suggeted the same to vlado, 3 or 4 years ago. And, he added it in the VRay 3.0.
This is very useful also for newbie people.
