Changing how a site looks

Two separate settings, and knowing which is which saves a lot of confusion. NAVIGATION belongs to the whole site: Sidebar (every space down the left), Top bar (a menu bar with drop-downs and a second row for wherever you are), or Minimal (just the wordmark, with Contents on demand). It is one choice for every page, so navigation does not change as you move around. LAYOUT belongs to each space — how that one page displays what is inside it. The choices are Showcase, File list, Dashboard, Story, Handbook and Shelf. A space inherits its layout from its parent unless you set one; Showcase is the default at the top of a site and File list inside it. Both are in the same menu on the space itself, clearly separated. You can also ask your assistant to set a layout (set_space_shell). To preview without committing, add ?shell=shelf to the URL for a layout, or ?nav=top for navigation.
