Next to "Insert Child Node" button add "Insert Multiple Child Nodes". When clicked, display a modal text area.. On click of OK on modal, create a node for each line in the text area. Similar request to: "Create Rapid Brainstorming List" ...but simpler: no drag-and-drop needed.. This would both speed creation of maps, and help guide planning / brainstorming: "For X, what are all the things we'd need to consider?" Select node X, type a list, and have the nodes added. Then repeat for additional nodes as needed.
