addurl.html was 116 words and five screenshots of a 2003 dialog, reached only from a single sentence in the guide. Its substance moves into that sentence: what the Add a URL button does that the address box cannot, including the browser-capture proxy, which lang.def confirms is still in the GUI. The stale screenshots go with it, and a fresh capture of that dialog belongs in the next screenshot walk rather than in a page of its own.
options.html had been an orphan since #661 gave it a legacy-list banner and repointed everything that used to link it. It becomes a stub pointing at the generated option reference and the command-line guide.
plug_330.html documents the callback interface of releases 3.30 to 3.40. Its title said so; now a banner does too, the way Fred Cohen's guide is labelled on the index, because someone arriving from a search engine reads the page and not the title.
