Add logs of loot amounts, OCR'd from the Loot screenshots, as well as calculation of how much the expended troops cost - can make a nice graph of wealth changes. I can help with that feature if needed.
if you can do this then my suggestion would be to compile the code and run a few tests and provide screenies. i say this as if your able to do it, then try and then the devs can ad it to the main code if it works or looks promising i guess.
