There are a slew of new features available in the OS X Lion, 250 to be exact. Phill Schiller, at the Worldwide Developer Conference 2011 demonstrated 10 of the larger and upgrade worthy features. Better touch gesture – Almost everything in Lion will be controllable by touch. You can use a three-finger swipe to cycle through apps, double tap to zoom, or pinch to zoom. If you’re used to using iOS, this should come naturally. Full-screen apps – Here’s another feature that iPad and iPhone owners will love. Apple made it easy for developers to make their apps full screen. You can swipe through multiple full-screen apps using touch gestures. It looks good. Mission Control – Mission control is Exposé meets Spaces. You can control all your work spaces from one easy panel. You can also activate Mission Control swiping down with three fingers. Built in Mac App Store – The Mac App Store will ship with the Mac App Store. Mac apps will allow for push notifications, in-app purchases, and sandboxing. Store Apps With Launchpad – Lion’s Launchpad will organize your apps. Launchpad is an iOS-like hub for all the apps you download from the App Store. You can activate it by clicking the app’s icon or using a four-finger pinch gesture. Save Your Progress With The Resume Feature – If you close an app, it will open where you last left off. All you have to do is log in to Lion and you’re good to go. Autosave Documents – Lion will automatically save all your work. You can also revert to last opened or other versions of the same file. View Old Files With Versions – Versions gathers all your autosaved documents and lets you look at all the previous versions. It’s just like Time Machine but for individual documents. Share Files With Air Drop – Air Drop is a built-in peer-to-peer file-sharing service. All you have to do is connect to the same Wi-Fi network and drag and drop the file to the computer you want to share with. There’s no additional setup required, and all your data is encrypted. New Mail app – The new mail app looks a lot like the Mail app on the iPad. There’s a two-column view with your inbox on the left and message preview on the right. It also has a conversations view, which shows you e-mails in the order you received them.
