I don't think the bluetooth and network icons should be combined - I (sometimes) use a bluetooth keyboard, and that's independent of whether I am connected to a wifi network.

I would like to see the bluetooth icon grey out when it's disabled though, rather than disppear completely.

And related to that, it would be nice if the icon bar at the top could grow if it had more icons in than normal - with the statusbarclock and the load-applet, it overflows to a drop down arrow. It should grow to the left (within reason)
