Google Glass is still a pre-release product that’s fairly rough around the edges, compared to a lot of shipping consumer hardware, but new clues (via Slashgear) from the latest firmware update suggest that there are a number of practical additions coming to the device. Those include a Glass app store dubbed “Boutique,” which would be a welcome addition for app discovery, as well as a locking mechanism that would let it be locked down when not in use using a swipe gesture code combo.
