Dividing Lines in Google's Navigation Menu:
To separate the search and the non-search properties, Google added two dividing lines in the More menu. Another change is that the services are no longer sorted alphabetically, but probably by usage. The order for non-search services is: YouTube, Google Calendar, Picasa Web, Google Docs and Google Reader, while in the search area: Google Video, Google Groups, Book Search, Google Scholar, Google Finance, Blog Search.
It's still difficult to understand why Google doesn't let you customize the navigation bar, the same way you can customize it in the new iPhone interface. This will probably encourage more people to use the menu and to go to their favorite services more often.
