Seems cheeky to ask for even more from such a great file! If anything:

– Some kind of carousel slider for images/content (I may have seen that already mentioned)

– Overlay style portfolio (like http://goo.gl/trcPyF or http://goo.gl/1g869k )

– Counters (like http://goo.gl/OLnZk8)

– Clients shortcode

Could not be happier with it anyhow though!
