This plugin modifies how author archive URLs are generated in a content management system. It is designed for site administrators and developers who want cleaner, more readable author page links that reflect a user's public identity rather than their internal username. By default, the system creates these URL slugs from a user's login name, which can be cryptic or unprofessional. This plugin changes that source to the user's chosen display name.

• Display Name Source: The plugin uses the user's display name field to generate the user_nicename slug, replacing the default behavior of using the login name.
• Automatic Update: The slug is generated automatically when a user's profile is saved, ensuring the author URL stays synchronized with their display name.
• Must-Use Plugin: It is installed as a 'must-use' plugin, meaning it loads automatically and cannot be accidentally deactivated by users in the admin area.
• Manual Profile Update Required: After initial installation, each user profile must be visited and saved once to apply the new slug generation rule to existing accounts.
• Improved URL Consistency: This results in author page URLs that are more consistent with the site's branding and user identity, avoiding potentially awkward or nonsensical links derived from login credentials.
