Apple unveils its latest desktop operating system: OS X Mavericks, coming this fall
 

Developer conferences have taken a turn in recent years, becoming as much an opportunity for companies to interact with the dev community as a platform for launching hardware outside larger all-industry shows. This year's WWDC, however, has been all about the software thus far. Apple has, as anticipated, given the world its first glimpse of its latest desktop operating system. The Mountain Lion followup shifts away from the big cat naming, to a California-themed release: Mavericks, paying homage to the giant wave surfing spot.

The first new feature is finder tabs: a browser-like system based in windows. Just add a tab by clicking plus in a window. You can also finally take the Finder full-screen. Also new, tagging. You can tag files based on location and other details, making them much searchable. There's a tagging sidebar that'll let you view them all in one handy place. Multiple Displays got a big cheer as well, letting you view menus across screens, viewing different apps in full screen mode on each display. You can independently pan on displays as well, and AirPlay connected HDTVs work a full, connected display. Apple showed off the new functionality to big cheers in the developer-packed room.
