The impersonate feature allows you to see your store from the perspective of a specific user. You'll see all the programs they have access to. So or example if you want to see exactly what a user sees when they are logged in, you can use the impersonate feature to accomplish this.
• Choose the Users menu.
• Select the 'Spy' icon next to the user you wish to impersonate. This will launch a new tab that allows you to see your store from their perspective.
