Here I am playing around with the tool. It's quite fun, and easy to use. Only.. downside is the lack of UV's and preservation of shader clusters on chunks.
Here is a growing tree proof of concept done with emTree by Mootzoid in Softimage. It has a lot of potential.
The only sad thing is I can't really do any UV's with it - unless procedurally, so it will only be so good for motion graphics, or non-animated growing trees.
I have concluded for smoother growing, I can make smaller section chunks in the tree. I've already given it a try, and it works.
To get the flowers, I used the growing trunk base then added the flowers as another growing tree - animating some parameters.
It's very flexible. I can control where it grows, randomize it, even work on making shapes in the chunks that can do what I want it to.
Not bad for a 9 year old plugin.
