Actually you can improve on the integrator params a lot by using this thread.
There are many new possabilities you can implement. The old method in this thread will be obsolete someday.

Have fun. I'm sure you will. It was a huge update when I added all of those.
I plan on doing the same thing with PowerPacker some time in the future.
I don't see the need for xp going away anytime soon. But I plan on doing the same for vista... or at least helping out. I personally hate vista and have not had a need for these types of things for vista. I actually get many customers who would rather have xp then vista.
I think XP will be around for a while. At least until microsoft fixes vista or maybe windows 9 will be better.
