-            Enables a toggle option in the submission interface to enable
-            auto-evaluation. When toggled on, the `eval` setting will always be
-            evaluated on job submission. An example use is the to-be-rendered
-            frame range, which by default automatically follows the scene range,
-            but can be overridden manually when desired.

+            A toggle button will be shown in Blender's submission interface.
+            When toggled on, the `eval` expression will determine the setting's
+            value. Manually editing the setting is then no longer possible, and
+            instead of an input field, the 'placeholder' string is shown.
