    It would be nice if the PDF I export from ArcMap supported turning on/off the layers like I can in ArcMap.  I know AutoCAD 3D Maps has this feature and it is very nice.  Instead of having to post a pdf map 3 different ways I could just post the 1 map and the user could turn on or off the layers they want.
