Selecting a controlling field

In the conditional field settings of a cck field, the labels for controlling fields are shown along with the allowed values for those fields.

In my use case, I have several fieldgroups with the same fields in them so all of the labels for the radio buttons are the same. It would be useful if the machine name also showed as well, so on line 371 of conditional_fields.module

'#title' => t($field['widget']['label']),

could be changed to

'#title' => t($field['widget']['label']) .' ('. $field['field_name'] .')',
