Properties vs List - Same or Different?

Though the properties palette is packed with information, there may be something missing. Here's an example of information that the list command reports that isn't available in the properties palette:

In Figure 1.0, there are four feature lines. The three red feature lines have been added to the surface, but the fourth feature line (the blue one) has not been added to the surface. How do I know that? It's all in the properties...just not the properties palette.
Figure 1.0
Figure 1.1 shows the information that is available in the properties palette for a feature line that has been added to a surface (such as one of the red feature lines in Figure 1.0):

Figure 1.1
If I run the list command on the same feature line (one that has been added to a surface), Figure 1.2 shows the information that is provided in the command line:

Figure 1.2
Notice that for this Civil 3D object, the properties in the "General" section of the properties palette don't appear in the list command results. Though some of the "Data" section of the properties palette is being reported in the list command results, a very useful property, "Breakline Data", only appears in the list command results and not in the information reported in the Properties Palette. The "Breakline Data" property lists the surface that contains the feature line definition in it and the breakline set. This information could be important if you need to delete this feature line but want to know if deleting the feature line will affect your surface definition.

Figure 1.3 shows the properties of a feature line that has not been added to a surface (such as the blue feature line in Figure 1.0).

Figure 1.3
Notice that for this feature line, the "Breakline Data" property has been omitted from the list command results. That's how I know that this feature line has not been added to a surface definition in this drawing.

Now we just need someone to come up with a slick customization so we can see all that info in the properties window. There really is no excuse, what do those 'extended data' and 'object class' tabs do? I've never found them useful.
