I'm not the first one to give a friendly critic concerning GUI of TG2. 
I also find it interesting when people say Bryce has a terrible interface which is totally self explaining...unlike the untouchable TG2 workplace. I still think it's a pity that they didn't copy more from Vue/Bryce so that even spoiled people like me would have the patience to learn the GUI. :-D
Nevertheless, I always admired TG renders; now it looks even more impressive!
