We'll create fresh WordPress site with Better Admin Users Search installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin improves the admin users search. Just configure what datas you need to search (or not) and that all 🙂
You can choose to configure what default wordpress search (login, url, email, nicename, display_name) and extends search with user metas (last_name, first_name…).
Free tip: this plugin do more sense with Admin Columns 😉
