The Swiss Army Knife of WordPress

I love this plugin! I’ve been using it for well over a few years now on multiple sites, and it has never failed me. There are so many places in a unique post or a page where you need specific code executed, and it doesn’t make sense to modify a theme or create a whole new page template just for that little bit of one-off code. Also, if you modify theme files, that functionality goes away when you decide to change themes, unless you patch and modify the new theme.
