Buddies, yes, the documentation is really code heavy and not thorough. It’s here:
https://ww.wp.xz.cn/plugins/features-by-woothemes/other_notes/
Essentially you have to place the shortcode [woothemes_features] in the place you want the featured items to show up. If I understood you correctly, you already did the first few parts (which have to be “gleaned” from the plugin). They are: 1) Add featured products to Woo Commerce if not there already, noting the URL of the product, 2) Create a Featured Post with only the title, featured image and the URL, 3) place the shortcode [woothemes_features] in the desired location and it will display the featured items. Additional code is listed for theme developers, but nothing easy. 😉 Mine worked, but they display vertically in Buro Theme. Working on it.
I hope this helps.
