While I want to include popular options by default, one thing is that builders can always just replace the textures included with their own (what I'm doing now to make these screenshots quickly). I plan on making 4-5 sets of the "stone walls", so builders would be able to get 4-5 sets of walls in their choice of textures in their work just by replacing textures, plus the stock of course.
