NEW IN VERSION 2.0.0: Users with a custom role will now only see the posts or pages they are assigned to. We’ve also streamlined the admin interface for easier configuration, and included additional instructions to help you get the proper capabilities assigned to your custom roles.
Custom Access Roles allows you to create, edit and delete custom roles for editing content. It was created to fill a need for a role editor plugin that is focused on providing easy-to-use admin tools for restricting content editing access. It is not concerned with restricting viewing access on the front end.
It is specifically intended for large sites with multiple content editors, where editors (by role, not individually) need to be restricted to only being able to edit specific areas of the site.
With this plugin, administrators of large sites have relatively fine-grained control over which user roles can edit which content, making it possible to manage a team of editors without concern that they will (accidentally or deliberately) edit content they should not have access to.
You can define a fully customized set of capabilities for each role, along with defining a specific set of post categories, pages, and custom post types to which those capabilities apply. For all other content, the role will have read-only access.
Custom Access Roles provides an easy interface for managing these roles and capabilities, with checkboxes for each capability grouped by the standard roles they’re associated with, plus checkboxes for each post category, page, and custom post type, presented in an organized hierarchy.

Custom Access Roles

Create custom roles with editing capability for only specific pages, categories and post types.

This is a pretty simple plugin. I wrote it because I have thousands of posts on my blog and I often have twenty or more posts scheduled to be posted. WordPress defaults to only showing you the latest fifteen (15) posts on the “Posts” list page. Now you can change this so you can view up to 9,999 posts per page. (Although I don’t recommend showing more than a few hundred at a time.)

David’s Admin Post Control

Allows you to control the number of posts displayed in lists in the WP Admin.
