This is a simple plugin that will help you register new Post Types and new Taxonomies.
No ads.
Registering a new Post Type you will have to fill a new name, if you want – you can change the slug or insert a description, select what type of post type you want: public or private. For additional options you can add via hooks.
Registering a new Taxonomy – insert the name ( note: a lot of names are reserved ), change the slug if needed or add a description, select what post type to apply this taxonomy and if you want it to be private or public. Other options you can add via hooks.
I made this plugin with less options because I like to add new post types and taxonomies with basic options.
In the future I plan to add additional features.

This plugin allow to build relation between 2 custom types (posts, page, custom), very useful for manage related content on CMS type website.
A few example use cases:
<ul>
<li>manually lists of related posts</li>
<li>post series</li>
<li>rented houses connected to agency</li>
<li>etc.</li>
</ul>
Relationships are created from a settings page from the administration console.
This plugin can not do relationships with users, you should test this excellent plugin made by scribu
