This looks good, thanks! It occurs to me that Annotation is a bad name since we're already using UpAnnots and DownAnnots, but that's not your fault. In a way, Annotation is the right name and we should come up with better names for the other two.

Yes, I was confused at first about what you meant by Annotation, because at first I saw only the UpAnnots and DownAnnots decribed in the docs. However, elsewhere in the code (I forget where) you call the 'a' an annotation.

Right, in the dual-tree documentation I think we call a an annotation.
