Unlike the desktop version of the Chrome browser, Chrome for Android does not show the forward and back buttons. But if you choose to use traditional navigation keys on your smartphone ...

While gesture-based navigation is the more fluid and intuitive ... By simply pressing and holding down on the virtual back button, you'll see a preview of the app or previous page peaking underneath.

I ask you, fellow video game nerds: Whomst among us doesn't crave more buttons to press? There's nothing especially fancy or unusual about Sony's new Back Button Attachment for the DualShock 4.
