The grid that shows how far you are in each tier in Cities and Knights Progression (Science, Trade, Politics). The colors are kind of dull and hard to tell which tier im in. It used to be a distinct green, yellow, blue, but now the saturation is much less. I prefered it the old way. Im not sure how many people agree but I think we should at least have the option to control the color a little bit. Also helps colorblind people.
