<p>Cornerstone makes WordPress practical for <strong>any type of site</strong> by enhancing its content management capabilities.  Too long have we had to resort to hacks like using categories in menus to build a pseudo site structure (you know what I’m talking about).</p>
<p>Cornerstone enhances your WordPress site in several ways.  One of the most useful features is one that allows WordPress to be used for sites that go beyond just blogging– <strong>Posts in Sections</strong>.  Create a section, add posts to it, they show up when visitors navigate to that section.  Simple as that.  It really is, but because you’re awesome <a href="http://archetyped.com/know/how-to-organize-posts-in-sections-in-wordpress-with-cornerstone/" rel="nofollow ugc">here’s a tutorial on how to do it</a>.</p>
<h3>Thanks for the Support!</h3>
<p>The support from the users that love Cornerstone is huge.  You can support Cornerstone’s future development and help to make it even better by donating or even just by sending me a nice message 🙂</p>

<h3>Features</h3>
<ul>

<li>Posts in Sections (see above for more info.  Why are you reading from the bottom up?)</li>
<li>Structured permalinks – post permalinks are based on the section they are in (e.g. <code>/section-name/post-name/</code>)</li>
<li>RSS for Sections – Let users subscribe to and receive updates for specific sections on the site.</li>

Cornerstone

I found the idea of this plugin quite useful so I was tempted to give a five star rating. But the permalink function is not fully configurable and does not work without trailing slashes which in some cases might be wanted. 
Since I found that a central part of the task the plugin should be used for is not functional I only gave it a 3 stars rating.



Does its job but breaks permalinks
