How To Display Main Menu on The featured area

Hi, By default Opigno installation comes up with a Box in the side bar where all Main Menu links are displayed. I would like to disable it and display the main menu in the Bartik Featured area. I tried to do that using the Structure->Blocks->Click on Bartik and then select Featured for Main Menu. When I click on Demonstrate block regions, i see the Main Menu in the featured area but on the home page and everywhere else it is still displayed in the homebox. Is there any way to change this? Thanks Srivaths
