Arbitrary layout are already possible, though the navigation
possibilities limit their use. It's not a priority as 3D layout is
recognized to be more confusing than helping but I saw some nice ideas,
for instance representing the time as the Z position. So it is in the
roadma.

Rotation and Orbit are not planned but rotation could be developed if we
find the time.

I was unable to solve the moving issue in the current engine and moving
nodes in 3D is not really working now. I think you are both more skilled
than me for these things.

You mean in 3D? I know the problem, though I don't exactly know why. I
can explain how zooming works currently however. My idea was to scale
the zooming factor according to the distance camera-object. More far you
are, faster you're zooming. As zooming works with the mouse position, I
know if objects are under the mouse ( I actually look for bounding
boxes). With this distance I get the zooming factor. This code is
probably not safe enough to handle negative numbers or something like
that, which may cause these issues.
