This was just the plugin I wanted, or so I thought. It doesn't actually come with instructions and I've clicked through all my wordpress and woocomerce settings, but can't figure out how to get it to work. In the woocommerce settings, there is a tab for styling the showcases boxes, but not actual instructions on how to get the damn thing to work. I am guessing that the instructions are in the plugin docs if you download the package. However, if you're installing the plugin directly from wordpress, then you don't get those instructions. Message to developer: maybe try putting instructions/shortcode in the wp details page as well as the installation package.
