AHK Script - Utility script for Window Arrangement in Real time

I need a script that stacks 20-35 windows on top of each other. And when I activate a window from the stack, I want it to be placed into a specific x,y slot, so if there are 10 activated windows - the 11th window that gets activated will be placed in slot 11. I also want the windows to be placed in order of importance worked out from a text extract from each window title. so most important windows in slots 1-8, next important in slots 9-20, etc. I also want the windows to be highlighted with a border and different colors for each window. I would also like to increase/decrease specific window importance via the use of 2 hotkeys. I will specify the co-ordinates. This utility will need to work on a dual screen arrangement. This project may lead on to more work if you are good. reliable and fast.
