SHOW AS is a Super-Admin tool in the left menu (group SUPER-ADMIN). It lists every user role/profile on the account; clicking one reloads the dashboard (/admin/?show_as_admin=<profile>) and, for the rest of your session, makes Sprwt treat you as a normal admin with exactly that role's permissions. It is the easiest way to check what a manager or kitchen staff member will see on the dashboard and which menu items and buttons they get. Because the choice is stored in your login session, log out and back in (or ask Sprwt) to return to full super-admin rights.
