dual-panel Chapter

[wnmartin]

Chapter 19 has four scenes in Panel 2 and then three back in Panel 1 and then four back in Panel 2.
The annotations are presently organized by Panel, Chapter, Scene and at various times are sorted on the fields in that order.
So, scenes
19.5, 19.6, and 19.7 are listed,
then 19.1, 19.2., 19.3, 19.4,
then 9.8, 19.9, 19.10, 19.11.
We want them listed in chapter-order, but with it possible for the proper panel/outline to be shown for each.

Additional observation: the suggestion is also to not indicate "Panel" in the list of annotations on the right, that is, the list on the right will not have "Panel 1", "Panel 2" listed as a "separator" bar link they do now.
