+- Every jail, filter, and action detail pane includes a collapsible **Raw Configuration** section at the bottom.
+- The section shows the complete raw text of the config file (`.conf`) in an editable monospace textarea.
+- The user can edit the raw text directly and click **Save Raw** to overwrite the file on disk.
