Google’s navigation bar widget that shows information about your account has been updated and now makes it easier to switch to a different account. All the accounts are automatically displayed, so you no longer have to click a link to see them.
It’s nice to see that Google went back to basics and removed the extra click. Multiple sign-in supports a lot of Google services, including Web Search, Google+, iGoogle and YouTube, so you don’t need to use a different browser or the incognito window to sign in to another Google account.
