After release of WordPress 2.5, the IDs on all admin pages have been removed as it was, probably due to the fact that the common user don’t need them. However, for advanced WordPress users / developers those IDs were quite interesting for some plugins or template tags.
What this plugin does is to display IDs on admin pages, showing the IDs, as it was in versions prior to 2.5

User ID has evolved from a simple column displaying user IDs into the most comprehensive Support and Debug Toolkit for WordPress available. Whether you are a site administrator, support staff, or developer, this plugin equips you with everything needed to inspect, track, impersonate, and debug WordPress users efficiently.
While preserving the core lightweight “User ID” column in the Users table and the <code>[user-id]</code> shortcode for complete backward compatibility, the 2.0.0 update introduces powerful, modular features designed to supercharge your WordPress user management workflow.
<h3>Core Features</h3>
<ul>
<li>User ID Column: Instantly see and copy User IDs directly from the WordPress Users table. Stop searching for ways to find WordPress user IDs.</li>
<li>Deep User Search: Stop relying on basic wp-admin search. Our advanced search interface is capable of searching users by ID, email, username, and even hidden user meta values inside the <code>wp_usermeta</code> table.</li>
<li>WordPress User Inspector: A detailed view of any user account exhibiting basic information, a full list of their capabilities, and a raw User Meta table viewer to debug exactly what custom fields a user has attached.</li>
<li>Secure User Impersonation: Need to test what a specific user is experiencing? Securely log in as any user (impersonate user) with a single click, without needing their password. Includes a persistent return-to-admin button and logs the action for security.</li>
<li>User Activity Log & Login Tracker: Keep track of user history. View log entries of when users log in, log out, update their profiles, or change passwords. View the last 10 logins directly on their User Debug pane.</li>
<li>Support Mode: An optional setting that enables a quick-access “User Debug” dropdown in the WordPress Admin Bar, improving support agent efficiency.</li>
</ul>
<h3>Developer Extensibility</h3>
<ul>
<li>WP-CLI Support: Use <code>wp user-id inspect <id></code> to instantly retrieve user data and capabilities from the command line without opening the dashboard.</li>
<li>REST API Endpoints: Integrates seamlessly with the wp-json endpoints via <code>/wp-json/user-id/v1/inspect/<id></code>.</li>
<li>Filters & Actions: Leverage hooks like <code>user_id_activity</code> and <code>apply_filters('user_id_meta_keys')</code> to extend the toolkit tracker functionality with your own custom events.</li>
</ul>
