I like the idea of Floating window layouts, presented by others, but I would prefer something Logos has already implemented with the "Home" button: pressing a single button it is already possible to switch among different "layouts": the Home page and the "working page". A similar behaviour assigned to another button (even better, a button series!) to which one could possibly bind two or more layout "chains" would be nice: acting similarly, each time one of such buttons is pressed, the current page would slide down and the next layout in the chain displayed.
