Do you like to write long articles with many headers? Then this is the perfect plugin for you. This plugin will add a link next to your headers so your user can share your posts pointing to specific parts. Plus a smooth scroll script is also included which will make the overall experience even better.
The package contains a predefined style for Git-like link display but it is hardly recommend to change the style to fit your needs (and your design).
The plugin uses internal cache which may interfere with other cache plugins, if you experience anything strange feel free to contact the plugin author.

The Striptease plugin changes WordPress’s default Read More teaser links so that they link to full posts.
WordPress makes it easy to break up long posts so you can save space on your home page. Simply insert the <code></code> quicktag while editing a post, and WordPress will display the text that comes before it as a teaser followed by a Read More link to the rest of the post. When a reader follows the link, the single-post page is loaded and the browser jumps to the unread text.
This jump can be disorienting, and some bloggers prefer to link their teasers to the full posts instead of the unread text.
That’s where the StripTease plugin comes in. It automatically strips the #more fragments from the end of your teaser links and turns them into links to your full posts.
<h3>Example</h3>
The StripTease plugin automatically changes your teaser links from this:
<pre><code>http://guyfisher.com/2005/09/striptease/#more-6
</code></pre>
To this:
<pre><code>http://guyfisher.com/2005/09/striptease/
</code></pre>
