Yet more new features from Google? [Updated again]

I was reading John Battelle’s blog just now in which he reports on what appears to be yet another new feature from Google that provides travel information if you input two cities, e.g. Madrid London. I tried it out with Chicago. As I input the term ‘Chicago’ I noticed that Google started anticipating what I was typing as well as providing combinations of search terms like Chicago Cubs, Chicago Tribune, etc. And that each search term gave number of hits to the right in real time. This is bizarre.

[I just realized after quickly testing this in IE and Mozilla that this "feature" appears to only be working in Flock (I'm using 0.4.9). 10/26/2006: Stupid me, I realized just now that this auto complete feature comes from a CustomizeGoogle extension.]
