Things like setting the color of palette or transparency of the background are not very important in a financial app, and making them options is overkill and only complicates the application logic.
It should either be implemented correctly, and readable for everyone on every kind of PC by default (including those with crappy old gfx cards), or not in there at all.
Upon second thought, your absolutely right. Then again it is a GUI wrapper so...
Maybe, one day when I get of my lazy ass, I could branch my own with the pretty features I like =)
