The system has added so many 4th and 5th cousins that it is impossible to navigate the tree.
My great-great-great-grandfather's sister married someone who has > 4000 connections.
When I turn on direct ancestors only, that helps, but I'm still showing > 7500 people.
It is easy to add parents to a node, but once they have parents assigned how many more times am I going to use that button, compare to how many I might want to navigate to that parent. But no visible control for the common action.
Nothing useful in the help about navigating your tree that I could find, beyond scrolling.
