The ListProp just uses a GPointerArray for its data, that could hold
structs rather than strings.  A function from those to strings could be
used for display.  They have their own properties, but the property types
would be the same for all elements, and thus describable with properties a
la FrameProp.

I don't know that they'd need more than the normal operations associated
with properties.  Which other operations were you thinking of?
