Something I found very useful in Divi by Elegant Themes. They include a header element builder. Simillar to the way the Enfold Footer Builder works. This would involve having a range of new ALB elements covering things like Site Logo, Menu Bar, Social Icon Block, WooCommerce Trolly Block, Search Icon Block and mobile rules available for these elements.
