Hi, I'd like to customize the content navigation box in monobook, here's a screenshot showing you what box I'm referring to in case it isn't clear. 

What I'd like to do specifically is add something similar (or even the exact thing, if this is somehow possible?) to MediaWiki:Wiki-navigation to this box. I'd also like to customize the help, community and toolbox boxes too so if you could show me how to do this it'd be greatly appreciated, thanks.
