Windows only: If the application dock on your friend's Mac fills you with envy, you might want to check out XWindows Dock, a full-featured OSX dock clone. XWindows Dock certainly isn't the first dock bar for Windows we've featured—RocketDock and ObjectDock are two popular options covered in the past. Although much newer to the scene than the aforementioned options, XWindowsDock has an eye-pleasing array of features. The visual appearance is easily customisable with settings covering opacity and blue, spacing, icon size, and many more aspects. If you're not interested in tweaking settings, the default is more than serviceable, and the application is skin-able to take advantage of other peoples' design chops. You can minimise applications to the dock, save folders to it, and even preview images and video on it. One small oversight is the lack of support for dragging applications to the dock to create shortcuts. Application shortcuts are added by searching from the dock for the executable. Not a deal breaker for most people, but if you're a frequent dock re-arranger you may miss the convenience. Also as you can see in the screenshot above, some of the default icons for applications come out a bit fuzzy—grabbing icons from the icon sets we shared last week would be a definite improvement.For more features and screenshots, check out the site below.
