Hi,
one more thing.
This is a very small bug, but still, I wanted to let you know:
After creating a Static Switch and changing it to "Define Symbol", the node still seems to create the keyword created under "Shader Feature Keyword", although not valid/used anymore (basically there are two keywords being created now).
This unused keyword however is only visible in the ASE (in the material properties), not in the compiled shader and therefor just a small bug, that has no effects on the actual shader.
Thanks,
Lars
