With Lion, Apple has included a way for developers to implement versioning control in their apps. So when you're saving files like documents you'll have access to both the past versions and current version. With a Time Machine-like interface, you’re able to view all of the changes in your documents and restore past versions if you accidentally delete something in the current version.

Spaces first appeared in OS X Leopard, but in Lion, the feature has been rebranded, along with Expose, into the new Mission Control feature. Mission Control is your one-stop place for viewing all of the opened application windows on your Mac, full screen apps and. Dashboard widgets. It also lets you create multiple desktops, which enables you to organize your windows by the types of applications or by the work you’ll do in each Space. Read on to find out how to best utilize Spaces.
