WordPress.org

Why was this plugin created?

This plugin was created to for the featured post management. Its easy and any minor wordpress developer or user can use and integrate into his wordpress theme with ease.

When I use this plugin to show featured post even when i am not adding "featured=yes" before the loop?

This is not a common problem, but this occurs when you are have called query_posts(***."featured=yes"); before the normal template loop like in category.php or archive.php or even index.php. So, its a good practice to add a wp_reset_query(); after each custom query you make adding "featured=yes". So why not add the wp_reset_query(); after the loop of featured posts.

What is this plugin exactly?

As mentioned earlier, this is just a simple featured posts management plugin that adds the post meta data as featured=yes for the particular post marked as featured.
