The Feature Custom Post Type Widget For Genesis plugin extends the functionality of the Genesis Featured Post Widget to allow it to work with custom post types and custom taxonomies.
You can download the plugin from GitHub and are free to use and edit it but please note, it is provided without support or guarantee.
It has been a while since the plugin has been tested and updated. One of the developers who contributed to the plugin, Robin Cornett, has since developed from scratch her own version of a featured content widget, that works with Genesis and other themes.
Therefore if you’d like to use a plugin that is supported and has ongoing development, please take a look at Robin Cornett’s Six/Ten Press Featured Content Widget (affiliate link).
