currently to view all the child of a character that has had multiple partners trough the year and child with more than one you can't see all of the "spouses" at the same time in the family tree unless you go to one of those child then you can see their half brother and sisters but not the mother of that half brother or half sister has shown if you look at the following family tree.   I suggest that all partners with which a character had a child be seen at once. the parenting line would have to be expanded horizontally to make this possible but it shouldn't be too hard to implement   This would be useful for the purpose of identifying why one half sibling has a title while the others don't by comparing the mothers or father of all of them in the tree view easily pinpointing where the noble blood may come from.   It might even be useful for society which allow people multiple partner at once to show all of the spouses at once.  

Dimitri's Response That is simply incorrect. Characters with multiple spouses have a set of arrows that allows them to navigate the tree based on the spouse.

 that is true however what I suggest is for them to be visible at the same time WITHOUT having to press on arrows.
