Starting from its beginning, GNOME-Shell has had a polished look and feel, but also a noticeable lack of features.
Obviously, if we are looking at what the developers are doing, this is not the end version of GNOME-Shell, but a "young" one which gains new features constantly.
GNOME-Shell 3.2 will probably feature:
- notification counters able to display your unread emails number (no need to go to your particular email client)
- persistent workspace switcher (when you have more than one workspace in use, the workspace switcher is visible)
- transparent window picker (Windows 7-like stylish decoration to windows when in Activities Overview)
- new fancy login dialogs
- integrated contacts search into the "main" search area
- enhanced user menu with an interesting "Do Not Disturb" ON/OFF
- and much more
