Custom fields were introduced six months ago to allow you to store and recall any information which is not part of our typical data model. You can now create custom fields which display existing information or fields projected onto another screen. Think of it like a report or query running inside the custom tab or field-set, pulling data from an object linked to the document you have open. We also added our address panel (with mapping feature) as a possible custom field type to complement our existing custom fields (date, text, number, percent, quantity-unit, value-amount, duration, text, email, lookup text, look up list and so on). At the same time, an issue causing custom fields not to save or to save and not display was fixed
