This plugin makes it dramatically easier to enqueue scripts and styles. 
Manage it from a separate option menu page.
You can enqueue in <code>head</code> or in <code>footer</code>, enqueue in admin dashboard, enqueue only for homepage, 
enqueue for all pages/posts/categories/archives or enqueue for a specific page/post/category.
Choose from any script/style in theme folder or from a specific plugin folder.
