1 a way to recenter the symmetry pivot when you lose it, like in maya where you can grab the center and snap it back to the axis. I find that I lose symmetry unexplicably sometimes, and s pivot c pivot and smart resymm don’t quite work for me, always.
2 I 8th the idea of texture layers would be so great to be able to make all your subsurface scatter maps right in ZB, even if you couldn’t see them comped together.
3 hot keyable color sampler.
4 color cloner
5 layer merging
6 retopologizing small sections of your lowest level of subdivion, as opposed to having to redo the whole model to fix one bad star location or add an edge loop.
7 default document size to be at double (i’d guess that 98% of people would prefer the doubled size) having merge checked and group unchecked by default in export options. or better yet…
8 a one button press to set which program/programs you are work flowing from, so that UV’s are auto flipped for maya etc.
9 a way to save ALL your settings in a file so that Zbrush will open at your preferred document size with brush curves/export settings etc, ready to go.
10 the same exponential leap you made from Zbrush2 to Zbrush 3 : )
