What? The UI is totally fine. Just because it&#x27;s a grid of photos doesn&#x27;t mean it&#x27;s just &quot;an iOS app shoehorned onto OS X.&quot; The app is written from the ground up for OS X. It&#x27;s not just some basic half assed port of the iOS version. The UI is different. The editing tools are more powerful. The performance is blazingly fast. Go give the Photos app on Windows 10 a shot if you want to see what the competition is up to. <i>That</i> is a pathetic Windows (mobile) 10 port.
