Instead of each wall having a legendary symbol it would much nicer visually to only have it on the left-bottom most wall, for all connected walls.
For example in the circled areas in the photos shown.

Ooh, that's an interesting idea. I wonder if it could apply to pipes as well?

How would this handle mixed qualities? You'd have to render the marker on all boundaries, otherwise you'd have unmarked walls that could be one of multiple options. Smells vaguely like the 4 color Theorem?
