It would make things easier if you could have multiple graph editor windows. I took a look at the graph editor code and it appears there are a lot of statics.
I’m not sure how much work is required as I am not very experiences with unity editor programming.
Being able to lock an editor window to a graph owner would be nice as sometimes you have two graphs that communicate through signals or events that you would like to observe at the same time.
I’ve recently been thinking exactly about doing that 🙂
So I can say that this is a planned “feature” to add in the future, but because it required a lot of refactoring, I cant really say when it will be ready.
