Display of apps across devices
How can I have the apps/icons appear consistently on all my apple devices? If I add an app on one I would like it to appear on all (and in the same order). It seems I used to be able to manage the order of icons easily on iTunes (move from screen to screen, etc) from my PC but I cant figure that out. Then I would love it if whatever I set could then could then synch across devices easily.
