Adding (or updating) the Awn-Testing PPA and installaing avant-window-navigator-trunk will include the Indicator Applet. Go to the Applets page of Awn Settings to add the applet. For full effect, also remove the applet from your GNOME-Panel (if any).
If you are building awn-extras from source, pass --with-indicator to autogen.sh after updating your branch.
The icons I'm using in the screenshots have been very popular among Awn users; they are from the Token icon set. I have organized collections of these icons for all the Awn applets and as many apps as I could find. To use them, download the archive and extract the files to ~/.icons/awn-theme/scalable - the icons should appear immediately. Download: Dark set, Light set
In case you haven't heard already, there is a new Awn style available, as seen in my screenshots, called Lucido. It is very stylish and it's available in the Awn-Testing PPA. Add Expander applets to define where the curves should be and change the "Curviness" variable to change how curved the curves are.
