Thanks for the positive feedback. We are pushing really hard on the features and also performance right now.

Sorry about the missing menu. We will have that menu back in the next week. :) Rendering options are still in flux as we technically haven't officially released that feature -- we've just soft launched it in a tentative state.

Right now you render via "Live Render > Fast Preview" in the viewport menu. Full information here:
