I am thinking about what I can do with the presentation of my wiki.

Can anyone recommend any extension for #MediaWiki that would allow you to add custom header elements above the actual article? As well as some examples of how this looks in actual practice?

Ideally, I'd want to use the content of some custom namespace for this - pointing to my books, interactive maps, interesting tale categorize, and so forth.
