Indeed, it exists and works. I just get a warning when I call [super 
changeSaveType:sender] but it works as advertised (well from you, Apple 
keeps it hidden!).
Perhaps the best thing would be to add/remove from the accessoryView the 
options for each file tye and make it totally dynamic.

Now  some further questions:
how do I get the current accessory view to modify it with my stuff? I 
could call "superview" on the sender which is the popupbutton, but it 
seems dirty. [savePanel accessoryView] ? I tried getting the 
accessoryView and making it larger, but it doesn't work, it is a NSBox, 
which makes sense under Mac. Perhaps the default one is not saved in 
accessoryView?

Second, in the changeSaveType method I need to know which filetype was 
selected. The document has not yet an updated fileType (hence the need 
of fileTYpeFromLastRunSavePanel of course).
A way would be to read directly the contents of the popupbutton, but 
perhaps there is a cleaner way. It appears to have the document name.

It looks like I have a clear idea of what to do, but getting list in the 
implementation details, I hate this!
