I thought one of the main issues they wanted to address was redesigning the landing gear, as the next gen engines that save all the $$$ won't fit underneath the wing!
Other than that, put the CB panels on the fuselage walls behind the FO and Capt, to create the space, and make it quieter! And redesign that stupid locker on the FO's side so I don't catch my fingers in it when it springs shut!
