Dr Bernie, I'm not sure what a shader rollback would be, though I do trust it is something I would want, judging by the other items put forward.  Is there a more detailed description of what this would be?  I 1000% agree about the idea of putting a checkbox to disable SSS in the render room.

Tsarist, I trust you already know about the Luxus for Carrara plugin, yes?  I understand there's a new update already submitted to DAZ for implementation that should add more features.  I've barely started playing with Luxus to find correct skin settings, but it does seem to export to Lux for rendering pretty well, and there is both an OpenGL version (for those who have monster computers with video cards that allow GPU rendering) and a non OpenGL version (for those poor souls like me that don't have access to higher cost computer equipment).   This is not to discourage Reality from making a Lux plugin, but just thought I would mention there is already another plugin that will work if you want to render unbiased in Lux.

I suppose dynamic cloth would really be more of a complex added feature to put in a request in this thread. 

However a knife tool for the modelling room seems like an easy and quick thing to add, so I'll go with that for now, and add more as they occur to me.
