Thanks for posting this list.  I just want to clarify one place where 
you quote me:

I actually said that a GUI should "be able to" do these things.  My only 
objection to the proposed function is that it's not sufficient.  R 
should supply facilities that make it easy to write that function, by 
supplying the mechanisms for the GUI to get at everything necessary.
