The merchant signs from the Library of Esoteric Artifacts are really great, however there are missing some, that really should be in it.
Carpenter and Artisan to name the two most glaring omissions.
But others would be awesome too: Post office, Warehouse, Temple.
Likewise, the Waymaker signs would be great with one showing up and down, maybe at a 45 degree angle.
Finally it would be great if it was possible to color the background of the signs, to make the sign itself stand out better.
