I'm building a family tree through LibreOffice Draw
I didn't know that the connectors automatically draw lines from box to box! For years, I'd been seeking software that could do this. The line-connecting behavior is a bit weird and unpredictable, but it's still fun!
I like draw.io, but the killer feature I want is auto-layout. As soon as a flowchart gets a little complex, things get really fiddly. I wish I could hit 'auto-arrange' and it would do some approximation of a tidy layout.
Darn, it's not on Windows nor Android. This sure looks beautiful, though, but the problem with family trees is that they need to be able to connect external boxes with their lines that are disconnected from the starting core, which is why mind maps generally don't work for them. Still, thanks for sharing!
It's great until you realize that it doesn't have some specific types of connectors you need or a way to control connectors path (you can't have connectors that go around other boxes).
