App Store History

Does the App Store have a history or at least a "Back arrow" button?
I thought I saw it in previous versions...

Previously downloaded would be accessible through one of the buttons below, I think. Suppose I'm checking out some apps, and I want to go back to one of the previous ones I visited - like you can navigate back to previous Browser windows. The iTunes Store has this 'Back' button, so I'd love to have it on the iPad AppStore.
