I agree with Daniel, it caught me off guard the first time that
document settings got in the way of undo-redo. Can't really tell what
other word processors use, but what I expected was that undo-redo only
applied to the text of the document. However, JMarc's point about not
being able to save after a setting change is very valid. If anyone has
libreoffice installed, how is this handled there?
