The default geometry of Automatic layout is probably good enough for hierarchies with straight-line connectors, but the results which it produces with orthogonal connectors are oddly distracting – making parent-child relationships less clear, direct, and symmetrical than they should be by default.
It's not even clear that it makes more efficient use of space. It sometimes even seems to waste a little space.

Consider, for example:

Problems:

1. Parents are not properly centred over their child ranges,
2. single children are often linked to their parents by jagged three-stage lines with redundant corners, rather than by simple straight lines,
3. and finally, the layout sometimes (depending on the tree) uses slightly more horizontal space than the simple centred layout below (which is generated by an Applescript).

I wonder if this could be corrected in future builds/versions ?
