Extensions will allow Chrome users to customize their browser if they want, but such features will likely never be added as default to Chrome.

"Chrome has a minimal, slick interface," Boodman says. "In order to keep it that way, we need to have a high bar for features that we add to Chrome. We won't add it for a majority, or a big majority of users. [It should be good for] nearly all users."

During the demo, Boodman displayed an add-on that allows users to track new stories in their Google RSS Reader. The add-on appeared on a bottom bar of his Chrome browser, suggesting that the real-estate at the top of the browser will remain reserved for bookmarks only, and not add-ons.
