Description:

Customize the WordPress admin pages by selectively removing interface elements.

Extended Description

This plugin uses a combination of WordPress hooks, CSS (when possible), and Javascript (last resort) to removed specified admin interface elements. These elements may be considered by some to be superfluous interface elements that are undesired for one reason or another, so this plugin aids in their visual removal.

Each admin interface element is individually selected for removal. The elements that can be removed are:

  • The header WordPress logo (bear in mind this functions as a menu) in the admin bar
  • The home icon next to your site’s name in the admin bar
  • The “Howdy,” greeting before your username in the admin bar
  • Your username link to your profile in the admin bar
  • Your avatar in the admin bar
  • The Dashboard menu link in the sidebar
  • The contextual “Help” link
  • The footer links
  • The WordPress version in the footer

(There is an associated screenshot which points out these different sections.)

Note: These settings are global and will affect all users who are able to visit the admin pages.

Installation

  2. Activate the plugin through the ‘Plugins’ admin menu in WordPress
  3. Click the plugin’s ‘Settings’ link next to its ‘Deactivate’ link (still on the Plugins page), or click on the Appearance -> Admin Trim Interface link, to go to the plugin’s admin settings page. Customize the settings to selectively remove admin interface elements.

Frequently Asked Questions

Q. Does this plugin allow for each admin user to customize the admin interface to their individual liking?
A. No. The settings for the plugin apply to all users within the admin pages and not to each user individually.

Q. Why is the admin dashboard still accessible?
A. This plugin does not prevent access to the admin dashboard; it merely provides the ability to hide the admin sidebar menu button that leads to the admin dashboard.
