Hello, would there be a way to reduce the size of these interaction handles via python programmatically?

Thanks a lot

Better yet, would it be possible to make the interaction handles appear only  
when I click on the plane node?

Thanks a lot

The code to change the interaction handle size is:

```python
getNode("P").GetDisplayNode().SetInteractionHandleScale(1.0)

```

I’m currently working on a node “Focus” improvement that adds this exact feature. No ETA at this time.
