Hope this fits the bill
Anyways added and polished this a bunch... Of course there is a huge amount of stuff to tackle still.
It is a neatly packed .xsiaddon now, and its got a little menu button to create the basic ICE tree... I think other menus should be added for the most common Modifiers.http://gustavoeb.com.br/blog/wp-content/uploads/2011/11/MotionTools.xsiaddon
(feels good to see stuff of the last to-do list was actually done!)
* Instancer Root (for separating diferent point generations);
* Linear, Grid, Radial Arrays;
* Modifiers and Modulators:
*Look is not kept when switching between Step and End Point mode if Control Objects are used;
*Rotations are unwantedly flipping.
*Control Objects should be created automagically;
*Geometry and Curve generation should follow;
