This new interface really has me flustered. It seems like a huge percentage of options for basic stuff (like changing/customizing scenes and materials) is hidden behind lots and lots of menus and clicks.
Here's one I've not yet decoded: How do I copy the material I've put on one part to another part? I ask this because it used to be as simple as CTRL-C (copy) and CTRL-V (paste). Now it copies and pastes the part itself. Lame. This matters, since I'll often tweak the color/illumination settings for a given material, and then need an exact duplicate for other parts. Other than writing down all the custom settings/values (no way), I've not found any way to do this.
And I keep losing where to find the ability to simply rotate my environment relative to my part/assembly model. Doesn't seem very intuitive to me.
