DynamicTabs

The extension makes it possible to remove and/or add custom tabs (tabs are eg. the edit button, history button and so on). This can be done by either adding dynamic links to articles with the same name in a different namespace and/or by adding arbitrary static internal and external links. Any and all default tabs can be removed by specifying it's name in the correct section on the configuration page, either for ordinary users and/or from sysops.
