There is no code changing the order of menu items. The
items appear exact in the order mentioned in your xml.
Also, there is a <separator/> tag to "draw a line"
between distinct menu items in the same menu. E.g.
if you want to separate the "Exit" menu from other items.

No, this you have to code yourself. You may of course
let swixml help you by getting the menu items and calling
setVisible(false) -- I did not try this, though.

This is a pure java issue and has little to do with swixml.
Some subjects regarding this are: test which component
owns the focus. Also, you may (as I would do it) create
a Cut/Copy/DeleteAction and register this component as
TreeSelectionListener of the tree and CaretListener of
your text (not sure about this). Then you could remember
the "last selected thing" allthough a test for the focus is
IMHO necessary too...
