It works with Posts, Pages and Custom Post Types, giving you a really simple way to make one post refer to another. Not to be confused with automated “Related Posts” plugins.
It’s probably most handy for Custom Post Types, where you may want to display a list of similar items based on factors that are indeterminable for an automatic algorithm.
Current Limitations
<ul>
<li>It’s only a one-way reference for now</li>
<li>It’s limited to linking posts of the same type</li>
</ul>
If you need help or have ideas for more features, please use the plugin forum.
<h3>Coming Soon</h3>
<ul>
<li>Admin panel for changing some basic options</li>
<li>Linking posts of different types</li>
<li>More flexible rendering of linked posts</li>
<li>Ordering of linked posts</li>
</ul>
