This was done by using an array of representation types instead of a single type for a panel.
The first element of the array is the primary type of the panel, and the rest are secondary types
that can also be displayed in the panel.
PR feedback:
- added test to check number of segments in side panel for 3D only view
- fixed jumping to segment in 3D only view
- fixed exception when adding contour segment in 3D only view
