I just went a little bit around in the topology-features.
Sorry, I cannot see any improvement, in opposite, I discovered some major deprovements.:evil:
Retopoing works so far, but is much, much slower than before, especially topo-painting (using shift-LMB-method) is less than half as fast as before.
Additional what worked flawless under ZB3 is now buggy , buggy, buggy.
The created adaptive skin-meshes contains some holes, when using my easy-retopo-method with projecting the fine-details you will no more see your low-poly-topology when you have set all up for the final step etc.
What the f… did the programmers do there ? 
Did anyone from pixologic take a look into our topo-lab within the last weeks ?
2 months of hard discovering-work and now we are nearly back to stone age.
Thanks .

Maybe I am a little bit to tired in the moment and made some faults in my own techniques, but I am really in the mood to kick the .1-Patch right from from my system and go back to 3.0 !
