I've used most 3D software and as far as I'm concerned Bryce has probably got the worst interface on the planet, although Mojoworld is a close second. The Interface of TG2 is not finalized and the one you are seeing now is basically allowing you to get to the metal. The final version will be more polished and hopefully bug free. Also, there are other versions than "Deep" planned and these will have a much friendlier, though less powerful and adaptable interface.
