Newly built into the Finder for OS X 10.9 is the ability to have tabbed windows. It took me a couple of days to even remember that this feature was there. Once I did, I realized there was a lack of discoverability. There was no “new tab” button unless you already had at least two tabs open. This makes the tabs function reserved for those curious users who happen to already know it is there. Even when customizing the toolbar, there is no new tab button, unlike Safari.

Hopefully an update will add the ability to have a new tab button in the Finder toolbar, otherwise this function will never be widely used.
