There was talk a few months back of a compact mode in Chrome that would turn the URL bar into a contextual element. Now it's seeping into early builds of Chrome 13. Here's how it works:
Instead of showing a URL bar permanently, the user will have to double-click a tab to see a shortened version of the URL that is displayed with a hover effect, if you move the mouse pointer away from the field, the URL bar disappears. The feature has to be enabled via a flag in a recent Canary or nightly build version of Chrome 13. To activate teh hidden URL bar, users will also have to right-click a tab and select "Hide the toolbar"Besides killing the URL bar, the new feature also moves the tools menu, hides any extension and introduces new back/forward buttons.[/p]
