+1 for fading away.

We originally had the idea that for "swipe to go back/forward" or "column-
based navigation", one could simply swipe forward again to get back to the 
already entered/changed data if one has accidentally swiped back without 
saving (before navigating somewhere else). That's not as easily possible when 
using the back button, of course.

Google's apps for Android (those which do not auto-save) do use such a dialog. 
They all use a Discard/Cancel approach (though with completely different 
wording and even inconsistent button position between the apps, which is 
really bad design).
We haven't written about it in the HIG yet (we'll still add one guideline for 
that), but here's what I'd suggest:
"Discard your changes?" [Discard] [Keep Editing]". This makes saving take one 
more step, but we want to train users to just hit "Save" anyway, and it makes 
the decision in the dialog easier.
There is already a component for a slide-in dialog available (don't know its 
name, though, tbh. If you can't find it, ask Marco).

Cheers,
