Old XTools has a gadget that dynamically loads an info bar at the top of every wiki page, showing a subset of the information from the Page History tool:
- the number of revisions
- how long ago the last revision was
- the number of contributors
- the number of watchers
- pageviews for the last 30 days
- who created the page
- the creator's global edit count
- the 'main author' (Hauptautor)
- a drop-down list of:
- checkwiki
- Wikidata
- language tool
- dead links
There's more to add to this list.
