Earlier this week I reported on an "Easter Egg" (hidden command) for a Redline feature in DWFit, the zero client DWF viewer at Autodesk Labs. The question I didn't address is "Why an Easter Egg?"
The answer is now available at Beyond The Paper, the blog of Autodesk employee Scott Shepherd. In short, how redlining will work in DWFit is not yet settled (or shall I say, not yet hatched). Thus it is kept hidden unless requested, while the development team works out its exact nature.
