Thread:Project:Support desk/How-to add new tab to the "Top Tabs" bar?/reply

Use the hooks SkinTemplateTabs (for monobook) and SkinTemplateNavigation (for Vector). You can see the example of that in the following extensions: Extension:Collaboration_Diagram and Extension:Semantic Forms

And please if you have time write a bit of manual on that, I promise to help!!! The current programming documentation is very incomplete.
