Easily Embed Dynamic Lazy Loading Youtube Videos And More Simply By Pasting The Url.
This plugin does most of the work client side, and waits for the page to finish loading so embeds do not slow down your site. 
Shortcodes are not needed (but are available), just add a clickable link to the youtube video, and the plugin will find all the youtube.com and youtu.be links, and replace them with an embed.
You know how sites like discord let you paste a youtube url, and an embed of the video shows up? 
This plugin works kind of like that, while also working with playlists, live streams, channels, youtube search, etc.
YouTube has an organized url system, and this plugin recognizes it. 
Every youtube playlist id starts with “PL”, and youtube uses many other consistent url methods like this.
Now supports local pdf embeds. 
Now supports google doc to pdf embeds.
This plugin allowes you to optionally load assets from cdn.jsdelivr.net, to improve performance and load the assets from the github repository of this plugin.

This plugin lets you specify a header image for each post, page, custom post type or archive page individually, from your default headers and custom headers.
It adds a meta box in the post edit screens with the header selection and a settings field in the edit profile and each taxonomy edit screen. 
If no specific header is specified for a post it will fall back to the default selection. 
There is no change of template files necessary as this plugin hooks in the existing WordPress API to unfold its magic.
Thanks to Erik T. for the idea to this plugin!
