Magento Magik Featured Products enables you to showcase your featured products scrolled horizontally on home page for different stores. See the documentation for more information. If you run multiple stores using single Magento installation then you can showcase your featured products for each and every store easily.

For this extension to work as it is Attribute_code for featured product must be "featured".
You can set it from Admin > Catalog > Attributes > Manage Attributes.

For displaying the horizontal scrolling in the front end, need to add following block in CMS page -
{{block type="featuredproducts/featuredproducts" template="featuredproducts/featuredproducts.phtml"}}
