Thanks guys
I am not sure how to make the network editor more visible on top of the scene view but it can be done. Maybe thicker lines that are additive on scene view, etc.
It should work like so:
Network editor overlay:
Only scene navigation is possible (same hotkeys with Space).
Without using space, they navigate the network editor.
Everything else is network editor related
Toggle network editor overlay off for full scene view manipulation
Toggle network editor overlay on for full network editor manipulation while seeing and navigating the Scene View
