/*
Plugin Name: WP Enqueue
Plugin URI: https://github.com/boykodev/wp-enqueue
Description: This plugin makes it dramatically easier to enqueue scripts and styles. Manage it from a separate option menu page. You can enqueue in `head` or in `footer`, 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. It has never been so easy before!
