I know this sounds odd, but I'm trying to map out the family tree of a multi-family household. You know, the kind where there's parent-like individuals but they aren't actually your parents so you don't want to add an actual parent connection where there isn't one, or two people who grew up together and consider each other siblings despite having different parents. Currently, this isn't an option because the program doesn't let you split the tree, and it's incredibly frustrating.
