Looks good; I was worried about the lack of Executive Office (I got on last night when no one else was around) so I'm glad to hear it's not gone for good.
It might be wiser to make some of the overhead catwalks two spaces wide instead of one, to prevent traffic jams. Also, the new skin doesn't tell you if you're holding anything! I see this as a problem!
But otherwise things look pretty cool. I also noticed the meep herding; it might not be a new thing but it is pretty cool, except that you can push
them through fences, and
you can push them through fences. (aka. push them so they move through fences, and push them when you're seperated from them by a fence).
