Manage User Columns is a WordPress plugin designed to optimize user management by allowing administrators to customize the fields displayed on the user list page in the dashboard. This plugin enables the addition of new sortable columns, including a default 'Registration Date', and supports the integration of custom fields from other plugins or custom code. Users can easily toggle the visibility of these columns without losing any data, ensuring a flexible and user-friendly experience.

The plugin also features a simple interface for configuration directly on the users page, along with a searchable text box for selecting column values. For advanced users, it offers a filter to modify column values through custom callback functions. The Pro version expands functionality by introducing custom filters and various filter types, enhancing the overall user management capabilities within WordPress.
