Foren / Cotonti / Skins / Current category CSS

Hi;

Is it possible to mark with a different CSS a category that you're currently viewing? (So in my case I would have the "FORUMS" in menu marked with e.g. different color) It's a standard in other CMS, it requires some server-side logic. Is it built into Cotonti (and not used) or maybe there's a plugin which handles this feature?

I also heard that there's a plugin "category CSS". Is it working in Cotonti? It might be useful, but unfortunately only in Categories (not Forums or other parts).
