Auto-bookmarking highlights
When highlighting, offer the highlight to be bookmarked.
Highlighting is done to something worthy of attention and therefore having need for later recall and return. I am reading a 200 page document and I have liberally highlighted interesting parts of the text, many on the same page. Now how do I revisit those highlighted parts? I am having to scroll through the entire document page by page in full page view to do that. A bookmark created while highlighting would serve that purpose perfectly. The name of the bookmark would be entered by the user if he wishes (some default otherwise, eg, H1, H2) and should have the line number + page number combination offered as a suffix for the user to optionally prepend his name to (hopefully no-one would have two separate highlights on the same line), eg, "Design Pedagogy - l.15 p.59" could be the name of the bookmarked highlight that talks about Design Pedagogy. The part from the hyphen onwards would be offered by Acrobat. Or else one would need a Search-First-Prev-Next-Last method for hopping between highlights also. But named highlights as bookmarks are far better, they allow me to refer to the highlights and navigate to them too. If I don't want to name the highlight (for a one-page document, for example), the naming default, eg, H1, H2 would be used.
Of course, all bookmarks should be shown in the list in the order of destination.
