Apple has introduced a new "Browse by Category" section in the featured section of both the desktop and iOS App Store, allowing users to easily browse the store via categories in a more visually appealing way than before



From MacRumors:

Previously, users had to click on "Categories" in the upper-left corner of the App Store and choose from a drop-down list. The new collection is yet another move by Apple to increase the discoverability of apps in the App Store. For instance, searches in the App Store were altered to compensate for misspellings, making it easier for users to find what they could be looking for.
