+============================================================
+Feature: #83461 - Show fieldname next to title in debug mode
+============================================================
+
+See :issue:`83461`
+
+Description
+===========
+
+If the configuration `['BE']['debug']` is enabled and the current user is an administrator, the fieldname is prepended to the title of each field generated by the `FormEngine`.
+
+
+Impact
+======
+
+The correct name of a field is important to know for developers and integrators. Examples are setting up access permissions or configuration using TsConfig.
+
+Instead of looking into the source code of the browser, it is now enough to enable the debug mode for the backend.
