What you are showing us is Unity. Not GNOME Shell. That said, GNOME has a  
dash too (that is how it is called). In its overview mode. You can learn some  
effective tips on this page: http://wiki.gnome.org/GnomeShell/CheatSheet

Notice also that many extensions are available for GNOME Shell and can modify  
it in a drastic way (or not): http://extensions.gnome.org/
