<p>Add support for taxonomy with or without hierarchical. Choose the selector type for write post.</p>
<p>Allow to add taxonomy to any objects registered on your installation. This plugin can be coupled with the plugin ACF to a new term meta database that allow to create on fly any field need for the taxonomy. For example, for a “Number” taxonomy, you can add fields : number ID, date of parution, screenshot, etc !</p>
<p>This plugin is developped on WordPress 3.5, with the constant WP_DEBUG to TRUE.</p>
<p>This plugin allows you to add taxonomy just by giving them a name and somes options in the backend. It then creates the taxonomy for you, takes care of the URL rewrites, provides a widget you can use to display a “taxonomy cloud” or a list of all the stuff in there, and it allows you to show the taxonomy contents at the end of posts and excerpts as well.<br />
To boot, it comes with a set of template tags for those who don’t mind adapting their own theme.</p>

Easy to Use

Compared to the competition, the design and extensibility of this plugin is significantly better.  Its performance is better and it doesn't suffer from code bloat.  Its learning curve is a bit steep, however that is what really sets it apart from the others.  The support team is pretty responsive with tickets and the documentation is pretty good! I'll be using the pro version of plugin going forward for custom setups.

Cheers~
