There are plenty of plugins to show lists of posts, but if you only want to display a condensed preview of a post on any wp page, this is the plugin for you! The shortcode accepts the numeric id of any post as an attribute, and will display a preview that links to that post. This preview is generated with easily styled html. To show or hide the featured image for your single post preview, pass the attribute <code>showimage</code> with either <code>hide</code> or <code>show</code>. It’s pretty easy!
For fun, I decided to also build a widget that does the same thing; it’s included and can be used like any other widget. Why not?!
