Mark Gurman Reports Tabbed Browsing Coming To The Finder In OS X 10.9 

9to5Mac:

The new operating system includes major enhancements to the Finder application such as tags and tabbed browsing modes

This is slightly out-of-character. I had the impression Apple thought Finder was the wrong way of thinking about managing applications and files, as highlighted by Lion’s Launchpad and Mountain Lion’s iCloud file storage model.

Tabbed browsing, though, seems to be an enhancement that goes against the grain.
