This is very important to my use of mind mapping. It should be possible to represent the convergence of paths; often a single child node properly has two or more parent nodes.
Without this ability, it is only possible to map concept spaces in which ideas consistently and solely diverge, but reality commonly involves concept paths which can take multiple routes to arrive at the same end point.

It might be the same intent, but it was implemented as multiple roots which is different than multiple parents. I still don't the ability to do this correctly.

I think it's the same as: https://mindmup.uservoice.com/forums/200447-what-should-we-focus-on-next/suggestions/5778506-facilitate-multiple-parent-nodes

This might help with decision paths or scripts where two or more paths (parents) can lead to one solution (child)

This is how my mind makes its best ideas
