I regularly create landscape retaining walls in my drawings using the wall tool. The landscape wall tool has never really worked for me as it seem to be for very large landscape applications and far more involved to use, at least that has been my experience. I would like to see the ability to add a top cap to a regular wall via the OIP, perhaps providing a cap option of height and width. I have, in the past, used an extruded these but it's a real pain when the wall top is sloped vs level.
