Hi, what I'm testing (hence the comparison w. Inspiration) is the automatic generation of a diagram from the outline panel to the left.

Manual interventions are certainly possible, but they're not really what I'm after. (Diagram generation and direction switching are both automatic in Inspiration).

Switching style-sheet rather than just direction might, I suppose, be the best approach. The starting style sheet (for the top-down tree), has to have only two (North South) magnets per node to avoid strange lateral connections.

I should probably switch to a diagram style with 2 East West magnets per node, and a left-right direction.
