GNOME 3 Shell



GNOME Shell is the core user interface of the GNOME desktop environment starting with version 3,which was released on April 6, 2011. It provides basic functionality like switching between windows and launching applications. It replaces GNOME Paneland other software components from GNOME 2 to offer a user experience that breaks from the previous model of desktop metaphor, used in earlier versions of GNOME.

GNOME Shell uses Mutter, a compositing window manager based on the Metacity window manager, and the Clutter toolkit to provide visual effects and hardware acceleration.According to GNOME Shell maintainer Owen Taylor, it is set up as a Mutter plugin largely written in Javascript.



FEATURES : 

An overview at a glance

The Activities Overview is the portal to all your computing activities. Quickly accessible using the top-left hot corner or windows key, it provides a single place to access windows, applications and even messages. The dash allows you to see which applications are currently running and the workspace switcher can be used to group windows.


Integrated messaging

GNOME 3 incorporates a unique, built-in messaging system. Messages can be directly responded to from notification popups, and you can access your previous communications from the Messaging Tray which is always available from the bottom of the screen. This means that holding a conversation does not require repeated window switching.


 

Everything at your fingertips

Search is central to GNOME 3. Applications, windows, documents and even settings can all be quickly and easily searched for from one place. Accessing GNOME 3′s search is as simple as pressing the windows key and starting to type. This is a great feature for people who like things to happen fast.


Easy system settings

GNOME 3 includes an integrated, easy-to-use settings interface. Finding settings is straightforward, and can be done either by browsing or searching. The GNOME 3 system settings include everything that you need and nothing that you don’t.
