Show values from the default language record and other localized records if the edited row is a localized record. Often used in
tt_contentfields. By default, only the value of the default language record is shown, values from further translations can be shown by setting the userTsConfig property additionalPreviewLanguages.
The wizard shows content only for "simple" fields. For instance, it does not work for database relation fields, and if the field is set to
readOnly. Additionally, the table has to be language aware by setting up the according fields in ['ctrl'] section.
