As I've mentioned before,
Task Panes made their first appearance on the scene in March 2001, in Office XP. If you want to get the background on Task Panes, why they were added, and their role
in modern Office UI, read
article or, better yet, the
the UI" series.
Because of our oft-stated design mantra "everything's in
some people have speculated that Task Panes are not a part of Office 12. This is
not precisely true, although the content of many Task Panes have moved to the
Ribbon and the role of Task Panes in the product has become more focused. There
are many fewer of them, and the few which are left are more consistent in their
behavior and reason for existing. But I'm getting ahead of myself.
First, let's talk about the mechanics of the Task Pane as it existed in
previous versions. The Office XP/2003 UI includes a single, full-height pane docked to
the right side of the window. This single pane could show one Task Pane at a
time, and you could switch between the available ones using a dropdown menu at
the top of the pane.

The Task Pane was used for at least four different kinds of UI.
First, it could act as a place to show secondary document information based
on selection. The
Styles and Formatting pane in Word, the
Clipboard, and the
Watch Window in Excel are good examples of this type of pane.
Second, the Task Pane was used as a kind of replacement for a wizard when it
was deemed important to have access to the document while running the wizard.
Mail Merge pane in Word is an example of this.
Third, the Task Pane was sometimes used as a replacement for what should have
probably been a dialog box. The
Attachment Options pane in Outlook 2003 WordMail
is an example of this.
Fourth, the Task Pane was used to show a set of visual choices, such as the
Slide Design pane
in PowerPoint 2003. These were mostly items moved out of dialog boxes so that
the results of the visual choice could be seen without blocking your document content.
So, it already wasn't totally clear how the Task Pane was to be used. Adding to the confusion was that a number of the Task Panes had automatic
launch behavior. This could be frustrating. For example, the Clipboard pane
took over that space if you happened to press CTRL+C a few times in succession.
When we designed the Ribbon, we knew we had to reconcile it with the
role of Task Panes. We considered removing all of them from the product
entirely, but there were a few which did seem to make sense within the new
design. So we struck a set of design principles to govern when and how would
allow the use of Task Panes:
The goal was to provide a predictable, consistent experience in which you are
in control of what windows you see as part of your workspace. The Ribbon remains
the one place to browse for functionality--there's no deep well of Task Panes to
spelunk into. On the other hand, the panes that some people do love--such as
Styles and Formatting--remain a part of the experience that you can turn on if
you wish and we won't interfere with it through "auto" behavior.
Finally, to clarify the developer story: we added the ability to use the Task
Pane in custom solutions in Office 2003 as part of the Smart
Documents developer story. The good news is that this capability still
exists and, in fact, has been upgraded pretty substantially in Office 12 as
