This plugin allows you to add your custom js and css by simply dropping your .js and .css files in the plugin directory wp-content/plugins/include-styles-and-scripts. There is zero configuration. You just drop the files in the plugin directory and it automatically includes it basis file extention (.js or .css)

This can be useful for adding your custom css or js file to any out of box themes with no coding.

Feedback appreciated on the project page - Include Styles and Scripts.
