Would it make sense to open the Editor automatically when you use the Add Genome Modifier macroscript? The Preset one covers the case where you are directly loading a preset and so don’t need the editor window, but it seems like 99,9% of the time when you add an empty modifier you want to open the editor immediately.
I think it makes sense.
EDIT: Done for single and instanced modifier. Won’t open editors if adding to multiple objects without instancing.
I also changed the logic to instance one modifier to all selected objects by default, and require SHIFT to create unique Copies.
I think 90% of the time we want one Genome, esp. now that we support all the Node Transforms correctly.
