As a user, I want to be able to quickly navigate through changes (diffs) of content.
This is particularly the case for the header-area, which is likely to be regularly edited. Possibly also for topic-summaries.
should have ← Older edit and Newer edit → links, like
including edit filter tags, eg https://en.wikipedia.org/w/index.php?title=Democratic_Party_%28United_States%29&diff=prev&oldid=594455920
