I played around with the new material shader builder and I'm wondering, how I get the OGL (surface/displace/environment) stuff when I'm starting from scratch.

All premade materials in the the material gallery have this OGL tab.

You need to manually add those rendering parameters via the nodes “Edit Rendering Parameters” menu item (gear icon in parameter dialog header). They are in the SHOP/OpenGL category in the tree list. Each parameter belongs to a group of parameters (such as Specular) and selecting one will add all of those parameters, so it should be fairly painless to set up.
