   Check.

   That's not true for Cocoa's NSToolbar. You can validate individual 
items, though, if you meant that.

   Wasn't true until MacOS X 10.2, IIRC.

   Not true at all on MacOS X. You can show/hide it, You can switch 
between Text & Icons, Text Only or Icons Only, and you can switch 
between two sizes. But you can't tear it off, nor can you make vertical 
NSToolbars.

 This is actually supported in MacOS X's NSToolbar, and used in many 
Preferences windows on the Mac to switch between the panes. In 10.3 they 
even added a "selectable items" list and a way to get/set the selected 
item, which is then highlighted with a grey background.
