The proposal is that if a child was born out of wedlock, or adopted, or out of prostitution, these relationships should also be visible in the main data fields, and not to be "gathered" or "understood" via the biography only.
In other words, marriage equals adoption equals concubine equals even same sex relationships [I know - blasphemy in da house] as far as the appropriate fields go, only to be somehow differentiated by a color code.
Bottom line - it is a drag that many relationships can only be "explained" in the bio's, whereas a simple "relationship-status" field in among the main fields as name, dob, place of birth, gender, dod [etc.] would make in once glance the picture a lot clearer. In this way WikiTree would reflect the reality out there, and not just the traditional "married" relationships ...
