Dieter Z. points out some of the background behind multiple level undo which is now part of Project 2006 (keep the stories coming Dieter) and relates how a customer exclaimed "Oh My God..." when it was demo'ed at the recent project conference. Despite the extensive work required to implement this I'm guessing that the response was less an appreciation of the technical complexity involved than it was a recognition of the long unexpected - that is it was as if a teen-ager had just cleaned their room without being asked. Surprising and delightful, but quite overdue... <insert smiley here>
