Thank you very much, I've been playing with it this morning. Looks
kind of cool. I will experiment with writing a bundle next.
Do you know if there is a way to turn off the displaying of "public",
"private" and "protected" entries in the variables column for C++
classes? This seems like a waste of space for me, and not something I
generally care about during debugging.

You are likely referring to the custom data formatters, a feature in
Xcode which allows developers to customize the information displayed
for variables in the debugger data view. Simple, customized
expressions can be entered directly into the GUI using a simple format
string -- you can find more information on this in the help document
"Viewing Variables and Expressions", which can be found by:
1) Opening Xcode
2) Selecting "Xcode Help" under the "Help" menu
3) In the window that comes up, select the "Debugging" link on the
left-hand side of the "Xcode Help" document
4) From the nested content that appears beneath the "Debugging" link
(after clicking on it) select "Viewing Variables and Expressions"
5) From that page, scroll down to the "Using Custom Data Formatters
to View Variables in the Debugger" section
Or, you can just open the file directly at:
file:////Developer/Applications/Xcode.app/Contents/Resources/
English.lproj/Xcode_Help/Debugging/chapter_8_section_9.html
For types which require more complex processing, a mechanism for
writing a plugin bundle to generate descriptions for variables has
been provided. For developers interested in exploring this feature,
some interim documentation is located in the file
'DataFormatterPlugin.h', which resides inside the Xcode application
bundle
(/Developer/Applications/Xcode.app/Contents/PlugIns/
GDBMIDebugging.pbplugin/Contents/Headers/DataFormatterPlugin.h).
Hope that helps.

I thought I had seen an article about how to add your own custom
"Summary" to your variable types. Like when you have a variable of
type WindowRef and the Summary column in the debugger says
'title="Window" index=0'. I would like to do this for a few of my
classes.
