Darn, need to get back to work now... Here is one more nice feature that I tried out. You can now export any parameter from within the functions and it will show at the top level of material or terrain editor. This is really nice because you can now for example adjust parameters while looking at the full size terrain preview or manipulate some detail of a material function deep inside without opening the function editor. I love that. You can save snapshots of materials while you work and revert to a previous iteration with one click. There is also a snapshot feature for the whole scene.
