I see a nice, new icon in the 15 packages, named preferences-system-firewall-new. Unfortunately, the desktop file still references the old icon, preferences-system-firewall, thus all the hard work of the artists remains unseen. Would be nice to get that fixed for F15
The system-config-firewall package contains two icons: preferences-system-firewall and preferences-system-firewall-new. The -new icon has been created for the wizard and is used there. The new icon is using the normal icon as a base and adds a star to it. BTW: Which 15 packages?
