I have a partial solution: When you open the MM file in notepad, you will see how all of the nodes are programmed and read into the freemind software. I make sure that my first node contains: POSITION="right" Example: <node created="1658923938435" modified="1658923938435" position="right" text="Project overview"></node> When adding new nodes from this first sub-note, they will appear at the same side. (Equal to using left, obviously...)
