This is just a thought. Even Kriesi's own theme has a nav div with a scroll-to-top area with social icons.
To have a menu widget and the ability to incorporate that into the Menus section would make this theme complete...well, really it makes any theme complete.
Again, just a suggestion. Maybe add it to the next update, or to future themes. I didn't want to put this comment on Themeforest, because I really DO like the theme.
