Why did you rearrange the pause menu for Angry Birds Stella? When I play, I end up restarting each level many times to get the angles just right. This wouldn't be an issue if each game had its own layout. It even would be less of an issue (though still annoying) if every other game's layout had been updated to match. Below are some screenshots to demonstrate what I'm talking about.
I could do another post about the game close confirmation, but I'll just leave it here. Sometimes the "Confirm" button is on the right; sometimes it is on the left. This is also a source of frustration. Angry Birds Friends only has a single "Confirm" button (no "Cancel"). Given how the game menus are arranged, I have serious doubts that anybody is accidentally closing Angry Birds, but if you are worried they are, at least order the buttons consistently from game to game.
