Longer term I would like to see consolidation of object attributes like I proposed here:
http://techboard.vectorworks.net/ubbthreads.php?ubb=showflat&Main=32542&Number=160145#Post160145
So that fills, hatches, textures, brick shaders etc etc are not all SEPARATE attributes.
Putting fill/line attributes on the OIP, where they belong, is a step along the way.
