This plugin works in conjuction with the Theme Blvd framework to create shortcodes for many of the framework's internal elements.
The low ratings given by other users who are either confused or wilfully ignorant.
The theme author is trying to separate functions that shouldn't be in commercial themes and turn them into plugins. This makes things modular - which is great.
I use this with a couple of sites and it's excellent. I love that the short codes are in a plugin and not the theme.
