In a
PTC forum post I found this screenshot, supposedly from SMath Studio:

Yet, in the newest version of SMath Studio, i miss the following features compared to that screenshot:
- repeated title of the region at the lower boundary
- Triangles showing the direction
- Intentation of nested area regions.

How to get the appearance as in the first screenshot?
