The problem with the economy report is that it only shows three regions at once... which means a lot of scrolling through my eighteen regions. Also, since the numbers are white whether there's a surplus or deficit, I have to look up and down the numbers for each region instead of checking at a glance for green vs red.
On a side note, I recommend adding more colors to green/red; at minimum I'd go with yellow for zeroes and cyan for large surpluses (say, 10 or higher).
