All the volume columns have the option to change background color but there's no way to change the background of the price column which makes it jarring. Would also appreciate the option to change the text color in the volume columns because they can be hard to see, as well as the text color of price itself.
One last thing, it would be much easier to distinguish different volume levels if there were a way to add an outline of each volume bar in the orderbook columns, like COB/SVP, ETC. An option to change the color of this as well.
