Tabs for Windows Explorer
Firefox sort of spoiled me. It has so many customizations available that so many programs are trying to catch up.
I especially like the tabs features which has now been copied by Internet Explorer.
Now come tabs for Windows Explorer in the form of QT TabBar.
QT TabBar saves the clutter of having several Explorer windows open. QT TabBar also offers a lot of other small tweaks, like the drop-down preview you see in the screenshot and a few toolbar buttons that add entries like "Recently Closed" or favorites. It's a little peculiar to set up, so be sure to check out the Manual.html file in the download for install instructions.
