Customise connection looks
Now we have more connections to nodes than strictly hierarchical (yay!), it would be great to customise their looks. This way you can much better create a map (other than a tree), include webbed groups of nodes, or even 'hide' the inherent tree hierarchy the system imposes.
MindMup responded earlier that "If [connecting nodes] turns out to be useful and popular, we’ll probably extend it with arrows, line types etc." so here we go ask for it, because it sure is highly useful. I run into the issue nearly every time I use the tool. (Asking for a real reduction of hierarchy will be another thing to ask..)
you can now select line styles, colors and arrows for links between nodes — check out https://twitter.com/MindMup/status/904653423659900928 and https://twitter.com/MindMup/status/897087392846368768 for a demo
