@stuffe - 1) So the thinking is bad. :-) The concept of the World Wide Web is the opposite of such thinkings. Why would I try to use my mobile phone at home when I have my home phone? So let's block mobile phones when at home. 2) I don't have a native app, on my iPad, for managing my Keynote presentations. In Keynote, I can only save my prez with a new name, not delete neither replace my old prez.
