Thank you for this great and useful app! I think I might have found a small bug though. After the user opens the camera app to use the camera and then closes it, the functionality of the camera button shortcut disappears permanently until the program is restarted by saving the settings again. It would be great if the camera button functionality could be restored automatically when the user is done using the camera app.
I've found the half-press shortcut useful to switch between tasks without having to sacrifice full screen mode.

N900 Minority Report lol !
