Google's personalized homepage* removed the strange limit that let you add only six tabs. The performance doesn't decrease if you add too many tabs because each time you click on a tab it's like opening a new web page. By default, Google loads the most popular gadgets related to the title of a tab, so you don't have to browse the directory to add new feeds and gadgets. A cool way to find new gadgets and to preview them is the Gadget Preview Browser.
Now when you try to add a gadget from outside, there's a new page that offers related gadgets and an option to "see this gadget when you visit Google.com". I wonder what that means.
* When iGoogle was called "Google Personalized Homepage", I wanted a shorter name. Now iGoogle sounds too flaccid to be taken seriously.
