A bad panel design?
No amount of lights and warnings so-called improvements will help unless the pilot actually knows how the airplane and its systems work and actually pays attention to what they are doing and to the aircraft and what its gauges are telling him/her.
And any checklists are much the same. Brain must be on first. The main thing I find annoying in the QRH is its size had quadrupled due to poorly thought out attempted remedies to accommodate pilots who do not know the machine and how the systems work. Now it is a clumsy bulky 'airplane for idiots' book.
