Better overview over cost / surplus (White Giant)

Since I started playing Simcountry, the game often added and removed money (many times per month) from my country's bank accounts and I often wondered what exactly was it, that suddenly cost me 100B or what was it that added 100B to my account? I think a neat overview over what changed a country's balance would be useful to be able to decide what to do in order to raise surplus or to identify unnecessary cost. If a page like this already exists, I was so far unable to find it. The Financial Statement page is not sufficient to identify what exactly caused a loss or surplus in money. Something like a bank statement which you get every month (preferably in realtime) with exactly identifiable income and expenses would be useful.
Also: The "Recently sold" and "Recently purchased" pages serve no purpose - they display nothing, even if things were purchased or sold.

recently sold and purchased shows direct trade stuff.

Most expenses can be tracked down with a little detective work, look at materials sold/purchased, pop spending etc etc. Some things can be hard to work out though I do agree, and what math the game uses... who knows?
