You can manage all of your installed icon sets on the Icon Sets page. You can get to the Icon Sets page from the WordPress dashboard, by navigating to WPIcons ⇨ Icon Sets.
After the initial installation, the only icon set that should be visible to you is the Default Icon Set. This is the icon set that comes bundled with WPIcons, and contains over 450 high quality, professionally designed font icons.
Note: The default icon set can be disabled completley, so it’s not loaded on the front of site, on the WPIcons settings page. For help, see our documentation article How do I disable the default icon set?.
