Easily add schema valid breadcrumbs to your site. If you’re using RDFa Breadcrumb or Yoast Breadcrumb, this plugin automatically takes it’s place, if your using a supported WordPress framework, it’s as easy as enabling the plugin and checking the “Try to add automatically box”, if you’re not using one of those, adding it is as simple as adding one line of code to your template!
<h4>Supported Frameworks</h4>
Currently the breadcrumbs plugin supports the following frameworks out the box:
<ul>
<li>Thematic</li>
<li>Hybrid</li>
<li>Thesis</li>
<li>WP Framework</li>
</ul>
And is a drop-in replacement for:
<ul>
<li>RDFa Breadcrumbs</li>
<li>Yoast Breadcrumbs</li>
</ul>
If you dont currently use RDFa Breadcrumb, Yoast Breadcrumbs or a supported framework then no problem, its very easy to add the breadcrumbs output to your templates, just simply call the below function where you want breadcrumbs to output:
schema_breadcrumb();
Alternatively you can call the breadcrumbs with a shortcode:
[schema_breadcrumb]

This plug-in limits the classes WordPress added to navigation menus to only those desired by the Theme owner, 
adds a unique ID to each <code>li</code> and removes any empty <code>class</code> attributes.

Navigation Menu IDs & Classes

At least some aspect of this plugin seems like it should be available in WordPress core. 
I understand the rationale for menu items having menu-item-ID, but it's pretty practical for them to have the slug in there, as this plugin provides.
Suggestion for plugin feature - offer option for slug prefix.
Like if I have a menu item "updates" I may use the class "updates" elsewhere, but class "menu-item-updates" would target the menu-item for sure. Of course I can currently use double selectors.



1 for inclusion in core

To reduce the extraneous WordPress classes and add unique IDs to navigation menus.
