Hello jmm,
It doesn’t provide all the functionality you want but the script here ([url]Document Review Pane] will show you the document’s metadata and a comment summary of other annotations to the source document sorted by page.
It is also possible to send all the information and links off to a spreadsheet. It’s not quite as friendly but does provide an alternative way to view and sort documents by metadata (including annotations).
As an idea for the future I particularly like the way tagnotate shows text of highlighted tags as an extract of a pdf page.
