I'm playing in career mode. I have both "Tracking Station" and "Mission Control" at level 2.
(ref: http://forum.kerbalspaceprogram.com/index.php?/topic/93728-maneuver-nodes-in-career-mode/)
I still have no blue orbit lines and no access to maneuver nodes.
It seems something is missing - aside of those both. But not (well) documented.
What is it?
Or: If i do something "wrong": What (exact actions) do you have to do to get those blue orbit lines and right-clicks on them (which the forum and the ingame documents speak of)?
Which buttons should i press before or during an ascend to get them?
==================
Solution: As it looks in my saved game (repeatable), if you take off having "Stability Assist" active (with some "pilot" riding), you land in orbit having no access to advanced features like maneuver nodes. As soon as i go back into flying mode and switch off SAS, the orbit in map mode turns blue and i have the advanced options available. After that, it's possible to turn SAS back on without the advanced options disappearing.
Maybe that's some sort of bug.
