Add a logout link to the administration bar
Configure Add a logout button under Settings → POM Tweaks → White labelling → Admin bar. Select Enable, click Save, and reload a site administration screen.
Signed-in users receive a direct Log Out item beside the account area. It uses the normal WordPress logout URL and its redirect filters. The shortcut applies only to site administration; the existing account-submenu logout link is unchanged.
Clear Enable and save to remove the shortcut. Other toolbar controls remain unchanged. See Configure toolbar logout, greeting, and visibility for verification, scope, and troubleshooting.
