Common Document Structure Paradigm

Many websites (or documents in general) have the following general structure: (1) Table of Contents (2) Main text referring to: (3) Figures. Instead of being completely general about how content of a page, HTML (or whatever its successor might be) and future browsers ought to be designed to ``do this common case well.'' The simplest version might be: navigation bar across the top; scrollable left column of text with hyperlinks to figures; scrollable right column of figures, which automatically scroll to the right place when a left-column hyperlink is clicked. A few fancy features: Each figure has a "Hide" check box so that an arbitary subset of figures can be compared. Left/Right columns can be swapped to Top/Bottom orientation.
