It is frustrating when one wants to create symbols with the colors from polylines to polygons you have to create the colors 2 times. Not a big deal when you have a handful of attribute differences to color.
However when you have hundreds of different attributes it is very time cosuming.
I would like to see the ability to use the colors for a an attribute in one feature type used in the second feature that is not the same type.
Example. I have 573 unique line sections. I want to color all lines and points with same color based on the LineSection attribute. This can be quick and simply way to help find errors in data.
