I'd like a feature where I can track how much gold I have used and on what. Like how the silver accounting tab exists on the auction house. I wish a gold tracker tab could be added to the statistics page or village overview page.
It would be a really good feature that help you figure out how much you've spent in a day or on what has it been spent on. Then when you sleep and wake up to find 100 gold missing only to find that your dual used it in a gold spree, you won't be surprised and can grill the SOB about it.
Keeping track of it could be highly beneficial.
