This is exactly what I was hoping would happen!
In it’s normal use meego-harmattan swipe behaviour would mean a swiping out of an application would bring you back to the screen from which you started that appliction.
Which might mean you’d need an extra swipe to get to the screen you’d really want.
Now with the option of customisable swipes, you should never be more than one swipe away.
For instance on my n9 I’ll be using this swipe scheme: up = app screen, down = kill/close app, left = notifications screen, right = multitasking screen.
Much more unified and efficient behaviour I think.
I wonder whether there’s the possibility to use two or more directions of swipe to initiate an action also… ie. Left and right swipe together = start an application
Or even swipe macros which could be started by holding down one of the volume keys for a while followed by a series of swipes that then does something…
this ones probably just for the hardcore users though.

<snip>I’m wondering which, out of the suggestions that have been made so far could be implemented by the community (without having to re-write huge chunks of code that is).
The application specific swipes could probably be done assuming that the trigger to make changes to mcompositor.conf active is lightweight with no side effects.
Pretty much all the other suggestions look like they won’t be possible to me……
Oh hang on! All this swipe gesture stuff is developed in the open (gitorious/meegotouch/meegotouch-compositor*) ?! That’s pretty awesome.
