Add features with the rules

Hide sensitive data like passwords and PINs, create custom web links, highlight values that meet certain criteria, mark dates as events (expiration dates or recurrences), and more.

Pair couples of objects with the relations

Define also their roles within each relation, e.g. husband-wife, parent-child, company-employee, etc.
