I am really greatfull for the work you have done with MarginNote so far.
However, I am really missing some important features to organize the layout of the mindmap.
I already mentioned the feature, that when zooming out, details should dissapear gradually and topic names should get bigger, like zooming in and out of google maps.
Another important feature is the possibility to arrange the nodes radially or at least bilaterally.
What does the bilateral arrangement node mean? I don’t quite understand your needs. If there is a picture that can explain your needs, it will be more helpful for us to help you solve the problem.
