I have segmentation node with multiple segments. When I click on Show3D, they show up in 3D view and also in Red, Yellow and Green slices.

However, when I have many segments, I find it confusing to differentiate them purely based on colour. I want the segment names to be displayed next to the segments in 3D, Red, Yellow and Green slice views. That way, I can relate what the segment is based on its name.

How is it possible to achieve this?  
Thanks

The segment name is already displayed in the DataProbe window (lower left). It could be displayed elsewhere with some programming but usually the DataProbe is enough.

In order to display the name on the Slice Views and 3D views next to the segmentation, which parts of the code do I have to modify? Do I have to make changes to the Segment Editor module itself?  
Do does it have to do with the rendering?

A good place to start would be to look at the `DataProbe` code and how corner annotations in the Slice Views

For the 3D view look, for example, at how the orientation marker is handled.

İ would second a request to display segment name inside segmentation view, eg when someone hovers over and waits a few seconds.  
On remote sessions (eg zoom) data probe is next to impossible to use effectively.
