When more they try to make Carrara compatible with the Poser content, the software gets worst. A lot of features could be updated, like the Metaball Room (is the same since Carrara 1).
I'd like to see more animation improvements on Carrara, like fluids, fire, smoke, physics and particles. For modeling, Carrara's tools are better than 3DSMAX imho, but some NURBs are welcome. Dynamic Cloth? Maybe, but is not the major feature in my list.
I remember the paint tool in RDS, it's far easiest and better than C7. They could follow the same method.

Cheers!
