While you are waiting for the Gnome 3 impatiently for the April 2011 release, you could attempt peaking at new shell. Those who have had a go at it come away excited at the substantial changes.

Gnome 3 is powered to offer full customization in future with powerful extension system and the present limitation is only until the gestation period for Gnome 3 is completed.
