Thanks Stefan,

From the screenshot, it looks to me like the test app is not using 
the unified title/toolbar metrics, but Mail is.  Try checking the 
unified title/toolbar checkbox in IB.

Your understanding of the NSToolbarItemGroup is correct.  However, the 
view will not be automatically resized to fit the labels.  For now, 
you will have to size the segments manually.
