Today we bring you the first part of a series dedicated to what's new in Mac OS X Lion. We will go through the sections: Mission Control, Launchpad, system appearance and new graphical elements.

Mission Control

Exposure + Spaces + Dashboard ≤ Mission Control – This is how the equation expressing the relationships between the ways of managing windows and widgets in Mac OS X Snow Leopard and Lion could look like. Mission Control combines Exposé, Spaces and Dashboard into one environment and adds something extra.

Probably the first thing that can be noticed is the nice sorting of active windows into groups according to the application. Its icon shows which application the window belongs to. When displaying all the windows in Exposé, all you could see was a cluttered bunch of windows.

The second interesting novelty is the history of open files of the given application. You can see that history either by using Mission Control in the application windows view or by right-clicking on the application icon. Doesn't this remind you of Jump Lists in Windows 7? However, so far I've seen Preview, Pages (with Numbers and Keynote this functionality is also expected), Pixelmator and Paintbrush work this way. It certainly wouldn't hurt if Finder could do this too.

Spaces, or the management of multiple virtual spaces implemented in OS X Snow Leopard, is now also part of Mission Control. Creating new Surfaces has become a very simple matter thanks to Mission Control. After approaching the upper right corner of the screen, a plus sign appears for adding a new Area. Another option for creating a new Desktop is to drag any window onto the plus box. Of course, windows can also be dragged between individual Surfaces. Canceling an Area is done by clicking on the cross that appears after hovering over the given Area. After canceling it, all windows will move to the "default" Desktop, which cannot be canceled.

The third integrated component is the Dashboard – a board with widgets – which is located to the left of the Surfaces in Mission Control. This option can be unchecked in the settings to turn off the Dashboard display in Mission Control.

Launchpad

Viewing the app matrix exactly like on the iPad, that's Launchpad. Nothing more, nothing less. Unfortunately, the similarity may have gone too far. You cannot move multiple items at once, but rather one by one - as we know from our iDevices. The advantage can be seen in the fact that there is no longer a need to sort applications directly in their folder. An ordinary user may not care at all in which directory the applications are located. All you have to do is sort out their representatives in Launchpad.

System design and new graphic elements

OS X itself and its pre-installed applications also received a new coat. The design is now more sleek, modern and with elements used in iOS.
