You can see example of Featured Products at http://demo.revindex.com/ (you can login as farmer1 and go to Storefront page to see how it was configured).

Basically, here's how to add a Featured list in 4 steps:

1. Add a Category called "Featured" and deselect the Published checbox. Take note of the CategoryID number. Assign products to this category like you normally would do.

2. Then create a custom Product List template from the Configuration > Templates page (e.g. call it "Featured List") and in the HTML hidden OverrideCategoryIDHiddenField value set it the CategoryID number.

3. Now add the RevindexStorefrontProductList module control to the Home page (or whereever).

4. From the action menu, select Edit Content and select the new "Featured List" display template you just created.
