I have used ObjectDock for several years, and when ObjectDock Plus was released, I pretty much jumped to get the upgrade.  I would say that ObjectDock Plus is best know for it's addition of tabbed docks, which is a great feature to organize dock shortcuts into categories as I do, but there are some other great features in OD+ that are sometimes overlooked.

I frequently see questions asking about the advantages of upgrading to ObjectDock Plus, so here is a quick tour of some of features you will find in OD+.
 

Tabbed Docks

Lets start with the most recognized feature which is the tabbed docks.  The tabs make it much easier and convenient to organize your docks by having individual tabs for whatever type of category you would like.  For instance, I have a tab for "Graphics" which contains shortcuts to applications like Photoshop, Vue 6, etc.  I also have one for "Office" which contains all the shortcuts for Office 2007.
 

The tabs and backgrounds are skinnable as well, and you can even assign each tab its own style.  The tabbed docks can contain the same shortcuts, urls, and docklets as the standard version of ObjectDock.  OD+ also has taskbar and system tray support so you can add a tab which will show the contents of each.  This is very handy if you want to use ObjectDock to replace your taskbar.

Multiple Docks

Why settle for just one dock, when you can have two, three, or as many as you want?  You can create several docks for your desktop, and you can even have both tabbed and regular docks on the desktop together. 

You can set each dock to have its own configurations, and even its own background.  Each dock can be set as a drawer, to auto-hide, or any of the other configurations that are available in ObjectDock.

Fly-Out Menus

This is a really cool feature, and can make your desktop way more productive as well.  You can create a fly-out menu the dock and have it display locations such as My Computer, Documents, Pictures, and more.  When you click the icon a "fly-out" menu will appear that will show the contents of that location and allow you to browse through with quick and smooth animation.
 

Task Grouping / Taskbar Options

As mentioned above, ObjectDock Plus can display your taskbar in the dock, but this is also configurable as you can choose which windows to display.  You can choose to see all windows, minimized windows, or non-animated windows only.  If you have several of the same windows open, you can reduce clutter by using task grouping.  Task grouping will "group" similar windows together and make it easy to access them in the docks.

Colorize Backgrounds

There are hundreds of docks, including tabbed docks, available on WinCustomize and many of them are made to match specific WindowBlinds skins for a perfect desktop match.  Maybe you want to add your color though, and with OD+ that is possible.  You can change the dock background to the color you desire with just a few clicks of the mouse.  It makes it real easy to match your dock with the huge amount of skins available for your Windows desktop.

There are just a few of the features available in ObjectDock Plus I wanted to highlight for you.  You can find more information, screenshots, and video at the ObjectDock home page.  If you are a subscriber to Object Desktop, you can purchase ObjectDock Plus with a discount.
