How about a direct link from the page header to the source of the latest version, to avoid the need to either use edit or navigate to the current version via the history link?

+ I'd like this too (and might try to implement it). -- [[users/jon]]

+I just implemented this. There is one [[patch]] to the default page template, and a new plugin. -- [[Will]]
