So long Yosemite, hello El Capitan. Apple just announced the latest version of its desktop operating system, OS X (10.11) El Capitan, at its WWDC conference in San Francisco. And while Yosemite gave us a major visual overhaul, this time around, Apple seems to be focused on polishing its desktop experience. It's similar to the minor refresh we got with Snow Leopard (El Capitan is a rock formation inside Yosemite National Park). So what's new? Gesture capabilities, for one. You'll be able to swipe to delete messages in the mail app, just like iOS. Spotlight search has also been improved, with support for natural-language queries like "Documents I worked on last June." You'll also be able to juggle windows more easily by easily snapping them side by side, or by creating split-screen views (both of which seem reminiscent of Windows 8).
