Hi Ben!
Thanks again for pushing in that direction.
Here is the code culprit for the original behavior:
-=-=-=-=-=-=
ROOrthoVerticalLineShape>>drawOn:for:
...
midy := ((edgeBound corner y - edgeBound origin y) / 2) asInteger + edgeBound
origin y.
...
-=-=-=-=-=-=
I think the "/ 2" should be replaced by "* f" where f having should be
a float 0.0<= f <= 1.0.
This float should then be parametrizable obviously, with 0.5 as default value.
Actually, this code should be in a utility method that is tested.
Does it make sense to you?
Cheers,
Alexandre
NB: I am currently under various deadline. In two weeks I will be freer, meaning I will
look at the treemap layout of Dennis and fixes some more bugs.

With the Ortho layouts in Mondrian and now Roassal, I
find that it can get a bit messy when moving nodes around when each node pair has its
middle line segment spaced at 50% from each end. I have thought for a while that it might
even better if the middle segment could be shared among child nodes. So I've done a
basic implementation this, and there are a lot of rough edges, but I wanted to share this
before going any further to check if this approach is reasonable, or if there is a better
way to proceed.
A few of the things that need to be sorted are:
1. Distortion when a node is dragged up so that the top of windows stretches up
2. Arrows go a bit strange if the child is dragged higher than the parent.
3. The horizontal mid-segments need to be offset, otherwise the join together when a
child node is dragged to the far side.
Attached is an image showing the two methods side by side, and also the mcz.
