You can define the level on indentation for a high level feature, 
everything that has more is a low level feature. If the point is close

automatically as you move the point.

Ok. I guess I could use the number of characters as a distance measure.

reveal-mode? I'm running 21.2.1 and I don't have a reveal-mode.

It's the automatic hiding/unhiding that I want.
