I'm just scratching the surface of Creolabs right now, but the first impression is good. I especially like the speed of testing. Almost no compile time after the debug starts.
But, I wonder what this product is mainly used for? Is it mainly for prototyping only? I'm asking this because I don't see any (advanced) debug capabilities like breakpoint, stepping through and watch variables. Is this something that is in the works or is it out of the program's intended use case?
