When you write a long post, it is common to add h2 and h3 tags to create sections on a specific topic. This plug-in will search these sections and add a link to each of them at the beginning of your post. Each section will become a named anchor, allowing the user to browse quickly through your post. 
This summary is also understood by major search engines and should improve your CTR (click-through rate) by providing richer snippets.

wp_summary

wp_summary will automagically show a summary of your post at its beginning, using h1, h2 and h3 tags to create sections.

A small plugin which allows you to use nested shortcodes (i.e. a shortcode within an enclosing shortcode) by implementing a simple “do_shortcode” filter as per the WordPress Codex to content and widgets – see <a href="https://codex.wordpress.org/Shortcode_API#Nested_Shortcodes" rel="nofollow ugc">Shortcode_API</a> and <a href="https://developer.wordpress.org/reference/functions/do_shortcode/" rel="nofollow ugc">do_shortcode</a>
