Horizontal navigation bar, how?

Hi,

I found some issues about navigation at wiki and forum but I'm not satisfied. I would like to have a navigation strip on every page, something like this:

Home > User > Registration

I think that i don't need more elements (Home Page > Controller > Function).
I think, that I need assign descriptions to controllers and functions. Do you know any elegant solution (for example plugin) having similar functionality?

Thanks for any answers in advance!

BTW: how to get controller name and his function name calling from controller's function body?

Regards,
Tom
