Thank you, Carlos.
I thought so... too bad...
As you can imagine, when copying Macros we copy/drag all connection lines and this can be a complete visual mess.
What about visually grouping some nodes into one "Group Node" and creating a list of parameters for additional links, similar to the Attribute list with nested generators. Sure, potentially, it will be a large list but we could "clean up" the Style Editor Sheet drastically.
