Besides the fact that it's not working correctly if you are using a highly customized WordPress version with a complex theme, I can only read "Pro feature! Pro feature! Pro feature! Pro feature!" in the settings.
I would not even give 1 star if I could.

Dude, please.. You are enqueue jQuery UI styles everywhere and are breaking the styles of others plugins that use jQuery UI. You must enqueue it only on your page. And pay attention that WordPress already provides its styles of jQuery UI, you are braking some styles of WordPress core features.
On one of your plugins update you did this and break various plugin styles.
I'm stop using your plugin now.
The directions do not show how to use the plugin. Kindly post how to use the shortcodes please.
I download it, put it into plugin, activate it and... it doesn't work. Tested on fresh install of WP with Twenty Fourteen theme.
