Funny you ask. I believe there was. It's interesting because when I saw it, I thought "that could be a cool feature" when I saw it.
Give me time. I am out and about but I will dig.
If I recall, it was dotted lines or connections of connections.
Regardless, I do think it's a good feature for the reasons he stated. Just don't think it was necessary to share right now unless they plan to somehow get that built in ahead of the launch?? Which is supposed to be summer, so exactly 2 months.
