One year ago, Google Chrome came out of nowhere to re-ignite the browser debate. Today, it's reached (development) version 4.0, and it's anchoring a much-anticipated operating system. Here's a look back at where Chrome's been in 12 short months.

Want access to your Chrome bookmarks without adding a toolbar or relying on auto-complete typing? A quick command line switch—yes, another one—gives Windows Chrome users a drop-down bookmark button on your main toolbar.

To get the button, right-click on your Chrome launching shortcut, select Properties, and in the "target" field, add --bookmark-menu one space after the final chrome.exe. As the Download Squad blog points out, there are more than a few command line switches at this point to add new features, but you can add multiple switches to get all the features. That would look like chrome.exe --bookmark-menu --enable-user-scripts, for example, if you wanted both a bookmark menu and user script support.
