A much-needed link, especially on large active wikis with editors who have been
around for years, is a pair of "nearby contributions" links for advanced
wiki-users. The most important link is "contribs this user made around this
time" -- a jump to the appropriate part of that user's contrib history.
A second similar link would be "contribs in this article's history near this
person's edit" -- again, a jump into the history list around that revision;
something the diff-view of a pair of revisions should also link to.
Update:* revisionjumper gadget provides this.
