It is a simple suggestion to improve the workflow and reduce the size of a graph.
The current workflow (for me) is to create a grass texture portal, then I substract a noise on it (changing the seed and other values) for a total of 4 nodes per detail.
This not a priority suggestion but I think it could be an interesting improvement to add an optional noise subtraction right in the details or even allow multiple details in one graph (with their own noise / seed set per detail).
