+/**
+ * Gravity Shop // GS Product Configurator // Add Gravity Form Column to Products List
+ * https://gravitywiz.com/gravity-shop-product-configurator/
+ *
+ * This plugin adds a "Gravity Form" column to the WooCommerce Products admin list, showing
+ * which products are connected to Gravity Forms via GS Product Configurator. The column
+ * displays the form name as a clickable link that takes you directly to the form editor,
+ * along with the form ID for quick reference. Products without attached forms show "No Form".
+ * The column is also sortable, allowing you to easily organize products by their form
+ * associations.
+ *
+ * This enhancement provides administrators with a clear overview of product-form relationships
+ * directly in the WooCommerce admin interface, eliminating the need to check each product
+ * individually to see if it has an attached configurator form.
+ *
+ * Instructions:
+ *
+ * 1. Install per https://gravitywiz.com/documentation/how-do-i-install-a-snippet/
