Give an icon to the Gnome Shell 3.6 activities button

Question

In previous versions of gnome-shell in Gnome 3, it was possible to use an icon in place of the "Activities" text in the left upper corner. These tutorials tell how to achieve this, the second one even providing an extension. It does not work with gnome-shell version greater than 3.2, though. Can the icon be brought to the current version, too?

Answer 1

The Activities Configurator extension allows to modify, or even hide, icon and text.
