Another long time MindNode user here. I know the nested lists and map views are essentially two visualizations of the same structured data but my brain just finds the maps less thought-constraining. I end up with more creative paths in map view when I use it to plan.
I'm generally in agreement, but when I need to share something, the outline tends to be easiest to share with others. I'm really happy it's there. Maps for me, outline for others.
Horses for courses I guess.
Bike looks neat though.
