We need a type of custom field: Created by and another one Edited by and third field type for Timestamp. Thanks
Both “created by” and “edited by” would be ordinary single-line or dropdown text fields. See the Guide: https://www.manager.io/guides/8941.
Manager does not use time for any accounting function. However, you can rely on the History file to determine when entires were made. See https://www.manager.io/guides/29733.
