I would like to see a multiple click function in the materials room similar to Daz Studio, so that the user can change all the values of a figure at the same time.  An example of this would be with the specular value of a figure. At the present time the user has to change each one individually and ts time consuming doing these adjustments. 

probably use a script for that. Most of the skin shaders these days have spec hiding in Alt Defuse. @ hborre:  I NEVER use the ray trace preview. I have a low-res setting saved as a preset and render something that will fit in the screen. The ray trace preview is too small for me to see anything I need a preview for.
