Color Coding Palettes

There's been many discussions about the color coding method of palettes. I have to say, I am getting use to the outline method in Hog4. It is a nice clean way of coloring the palettes. I do think that the palettes in the Colour Directory could be different. I like how the color palettes in the Gel Picker Directory look. Is there any way that the Colour Directory can be this way?
