The new Big Lights theme is in development. It adds new lighting design options, and new block patterns, and it adds a number of new controls for designing the main navbar. The primary purpose of the new controls is to improve the layout when the menu is floated to the right, so users have more options when building smaller menus. This site and my blog are currently running on early versions of Big Lights. You can see a screenshot of some of the new customizer controls below.
