plugin for lightwave: TreesDesigner
TreesDesigner uses some initial mesh as the base shape, then grows leaves in the shape.
I wonder why you mention in on the blender support forum. As you would like it to be implemented for blender? The best way would be to contact the author directly :-))
Currently I have no plans to implement it for blender. If anything Modo is at the top of the list but you know how it is with full time job and kids… not much time to play with toys. I’m open for suggestions though 
For those of us with Lightwave on their system though, given Blenders LWO importer, it is a handy way to make trees.
