• Switch between different user roles to test permissions
• Send custom headers and body data (JSON)
• View detailed responses including status codes and response time
• Create multiple request tabs and persist state between sessions
• Auto-suggest routes with a searchable dropdown; auto-select primary method
• Generate example payloads based on route schema (via OPTIONS discovery)
