To register custom statuses for feature requests, visit Requests > Settings > General in the WordPress admin panel.
Custom statuses interface
Each status requires a status title, description, badge text color, and badge color. The Badge Text Color and Badge Color fields accept any valid HTML color value.
When a new status is created, it becomes available wherever statuses are choosable within Simple Feature Requests.
If a status is deleted and it was previously used on some requests, those requests will revert to Pending.
Note: If you have only one custom status and would like to remove it, simply ensure the Status Title is blank.
