Set your anchor name in the options page.
Typical use case: a big picture in the header you don’t want people 
to be bothered with every time they click on an internal link. But 
you still want that beautiful picture to be there.

Very simple plugin that adds an anchor to page and post permalinks, which can point to an existant anchor in your template.

The Paragraph Level IDs plugin adds an ‘id’ attribute to each paragraph tag in a blog post, giving the author and readers additional functionality.
So for example, becomes .
These additions allow anyone to link directly to that paragraph in the post. This is especially useful for long tracts of text, academic writing, and legal documents.
<h3>Road Map</h3>
In the future I hope to make the following improvements.
<ul>
<li>Streamline the code so it is at its most efficient and smallest file size.</li>
<li>Further customisation options for the id</li>
<li>A degree of backwards compatibility and localisation for other languages</li>
<li>An option so this feature is only applied to the post types specified.</li>
</ul>
I would welcome any advice, offers of support, bug-testing, forking the project and troubleshooting to help make these extra features possible.

My friend @strangerpixel overhauled the 0.2 code for this 1.0 release.
The comment by s_ha_dum in [this Stack Exchange thread] (http://wordpress.stackexchange.com/questions/74558/automate-paragraphs-in-a-post-page-to-have-a-unique-anchor-link) and the comment by Milo in [this Stack Exchange thread] (http://wordpress.stackexchange.com/questions/90066/numbering-sections-and-block-level-elements-in-wpautop-wordpress-as-cms-for-l) got me started. The [Add To Post plugin (https://wordpress.org/plugins/add-to-post/) was instructive in helping me build a simple settings form.
