Reuse a field across twenty content types in Drupal and you get twenty independent copies of its display configuration. Change the label, the format or the widget in one place and the other nineteen carry on as they were. Nothing warns you. The drift shows up months later as a field that renders one way on an article and another way on a landing page, and someone fixes it by hand, twenty times.
Shared Field Display Settings lets a field opt in to being governed centrally instead. Turn sharing on in the field’s storage settings, nominate one bundle as the source of truth, and its display and form display settings propagate from there — globally, or scoped per bundle where a genuine exception exists.
Philip Frilling, lead back-end engineer, published it to Drupal.org in June 2023. It is one of the modules Oomph (now Pare & Co) lists as maintained rather than merely contributed to on its Drupal.org profile, and Drupal.org credits us with the initial development.
