I use the site primarily to create family trees for my fantasy world families/dynasties, which inevitably results in more than a couple incestuous marriages and relations. I get that this isn't that much of an issue for modern real-life families (especially if the trees don't go back many generations of ancestors), but I wish there was an addition that'd let us indicate more than one familial relation without duplicates making the entire tree clunky and overpopulated.
If anybody knows any tricks or tips on how to deal with this problem at the moment, please share them with me. It would be immensely helpful for my worldbuilding process. I hope the site finds a way to solve this issue one day.
