iPhone style, every menu function is visible in a bar or list to one edge of the screen.
If a revealable menu is available, may also present some key tasks in a Fixed Menu always visible on the screen. Doesn't count any old control on the page, just a set that are grouped and appear in the same place for the application or whole OS.
