Seems you have something in the works 🙂
I could see this feature working as a popup rather than truly expanding the nodes (subtree nodes being renderered on top of the actual graph nodes), meaning as a visual rendering of the subtree without the ability to actually select or modify the subtree nodes.
Let me know what you think about that?
As a side note, I do plan to allow multiple graph editor windows to be open at the same time as I replied to your other thread 🙂
