NSTabView alternatives

Are there any decent NSTabView alternatives? Preferably open source. Something that looks like the tabs in xcode4 (or any other modern tabbed application), support for drag/drop开发者_JS百科, close button, etc.

I was very surprised to find out that the SDK doesn't offer any besides the very limited NSTabView and searching for alternatives didn't produce any results. I looked into chromium-tabs but it seems like a bit overkill and complex.

Any ideas?

Thanks.

Many developers use PSMTabBarControl, which offers drag and drop, close buttons, customisable appearance and the like.
