I've bumped into a few snags running both of these.  They step on each other's toes.  Wondering if anyone else is running into similar issues.   It works great during 1 project.  But, when that job is done and you move to the next, or if you have concurrent projects (who doesn't?) the Material file thinks you have extra scrap pieces of the next formula-driven material.  The scrap manager database knows what is what, but you end up with extra panels in the material file itself.
