Some improvements have been added by Charlie lately with regards to procedural textures.
I created a thread in case anyone wanted to have a play and post results - keep everything together.
Doesn’t seem to have generated any interest at all - which is a shame. 
Here is a link to the build that contains these improvements:
I agree that Blender could do with more procedural textures and tools, however if this stuff is added and the community doesn’t get excited about it and doesn’t play with it - it doesn’t really send a message to the devs that such tools are genuinely desired or needed (and maybe they aren’t 
)
Charlie has done some great work on this (and has other stuff coming down the pipeline), yet I haven’t seen anybody else try his stuff out yet.
