Aside from the introduction of that system-wide dark mode in iOS 13, Apple is also making it easier to browse, view and edit your photos and videos. At WWDC 2019, the company showed off a new version of its Photos app that's designed to "remove duplicates and clutter and focus on your best shots." Powered by machine learning, this feature will put your best shots front and center, and you can narrow them down by selecting the new Days, Months and Years tabs. With Days, for instance, the pictures or videos that system thinks you'll like the most will get more real estate on your screen. And you can pinch-to-zoom to view all of your pictures in one go, as well.
