The plugin simplifies the WordPress admin user interface by hiding most of the WordPress menus. This doesn't mean that the functionality is not accessible. It is just hidden. Also the admin navigation bar is cleaned as well. The plugin is intended to be used by developers/designers who manage WordPress on behalf of their clients. Clients don't need to know or see anything about plugins, themes, available updates etc.
- Install, Activate & Enable the plugin
- Create a separate account for your client
- The client logs in and sees clean admin area
