One nice thing in latex2html is the next and previous
links, on every page. We could do a similar thing by putting these links
in the header or footer of each page. Similarly an internal link macro
to link to an arbitrary place in the current document seems desireable
(indeed this may already be implemented in HyperTeX, and all we have to
do is learn how to use it). We could use this, for example, to link to
a glossary and put all our definitions out of the main stream of the text.
