How do I save the state of a layout when I navigate from one layout to another?

Is there a way in which I can save the state (especially local and global variable, object properties) while moving from one layout to another?

I have a master layout to perform a few activities. Based on the activities, there are different games launched (as a new layout) from this master layout. After playing those games, I return to the master layout. This is where I want to ensure that the activities I performed before is retained.

Global variables will always persist between layouts. For objects you can use the Persist behaviour and they will keep their same instance variable values when go between layouts.
