Something I miss from some mid-90's HTTP servers is autolink functionality: when selecting text as an anchor for a hyperlink, a query would be run on what would now be called a CMS, suggesting possible targets. Not only was this convenient for the author, but also for the reader, as it encouraged more informative anchor text than the frequent-at-the-time "this" or "here".
(yes, link rel= navigation was also automatically supported, as were Imagemaps.)
