Stardock has released ObjectDock 1.3 (and ObjectDock Plus 1.3). ObjectDock is a program adds a "dock" to the Windows desktop. With ObjectDock, users can organize their programs, running tasks, widgets and much more onto their dock. This can save screen space and make accessing your stuff much easier. While functionality is what makes ObjectDock one of the most popular desktop utilities in the world (ObjectDock has over 2 million users worldwide), it provides its functionality in a highly polished way. The docks are skinnable, a variety of mouse-over effects are available such as zooming, glowing, spinning, and many others.
ObjectDock Plus adds the ability to have tabbed docks, multiple docks, and to display your system tray items as icons on a dock (eliminating the need to even have a Start bar using up space). The tabbed docks can be stuck to the edge of a screen where they can be hidden or display just the tabs on the edge.
ObjectDock is freeware. ObjectDock Plus is $19.95. Its home page is www.objectdock.com.
ObjectDock 1.3 adds:
-
Ability to offset the docks from the edge of a screen
-
Mouse activation (ObjectDock also supports hot spots). Mouse Activation allows docks to be totally hidden and then when the mouse hits the edge near where the dock is, the dock will pop on top.
-
Docks can now reserve the edge of a screen so that windows cannot cover them.
-
A ton of user-requested tweaks and changes to improve usability
