Screenshot of `App Store.app` showing title bar buttons out of place.

Why did Apple allow [the new App Store application][appstore] to ignore the [human interface guidelines][buttons]? It isn’t like the toolbar is doing anything radically different to other information browsers, nothing that might warrant exploring new interface ideas.

It just looks odd, an arbitrary inconsistency that would be simple to correct.
