I'll add my few words.
Don't know how to call it so lets name it "idle layout".
Basically i'm thinking about situation when you playing your game and for some reason you want to go to the game options menu to setup some stuff.
Now comes "idle layout" - you set your options menu or whatever on a seperate layout, checks options "layout is idle" and after that you can access that layout from everywhere from your game without worring about saving variables, positions for all objects and things like that.
Don't know if that makes any sens ;)
