This one might be stretching things a bit, but I figure it's worth asking. 😎
Currently when you "pour" a Dynamic Fill the edge of the line in the PDF stops the flow of the Dynamic Fill. Some linework in the PDFs I work with can be very wide. In most cases turning on "Disable Line Weights" thins down the linework to their centerlines, but not always.
My suggestion would be to add the option to have dynamic fill flow to the center of a line rather than the edge of a line.
