Cannot navigate Graph View

[hybridherbst]

Am I missing something, or is this just not implemented? For normal timelines, they become unreadably small very quickly:

Also, it seems that a Timeline is shown multiple times, as can be seen in this simpler example:

I think the five "outputs" on the left correspond to having multiple tracks, but shouldn't they all emerge from the same "timeline node"?

It is intended to improve the GraphVisualizer for this kind of cases.
Right now a graph is displayed for each PlayableGraph output (i.e. each Timeline track), but it's clearly not the way to go.

There's no way to navigate inside the view.
