Google made a small modify to the navigation bar used for its non-search services: the link to Google Reader was enthused to the "more" drop-down, while the link to Picasa Web Albums was brought back to the main bar. At some point, both links were incorporated in the main bar.
Google's Brian Rose said that the Picasa Web team is working on "some fun stuff" and we'll expectantly see some important changes in the near future. Meanwhile, Google Reader's team posted on Twitter that "the Reader link at the top of Gmail (and other sites) was accidentally detached. It's upcoming back soon, we promise."
It's still astonishing to see that Google's navigation bar is not customizable and you can't add your favorite Google services. Google experienced a customizable bar back in 2006, but this feature was quickly deserted.
