How can I reorder the items of the menubar?

[Keira]

I've used emacs before and it used to be that the first item on the
menubar was "Buffers", personally, I like having it there, besides
that a few other things where different, the filemenus for example.

How can I make the new emacs (21.2.1) behave the same as the old emacs
(20 or 19 something...)

Thank you,
