FWIW

had another thought/suggestion:  perhaps the developer could add "copilot" and "flight engineer options?

(1) this is one of the most impressive reviews I've ever read  -  really thorough and well written. Well done!!!!  (also - hats off to the developer!!!)

(2) You mention the enormous complexity at several points.  This is an appealing challenge, but I have two questions:

A. are there options to reduce/automate/simplify some of the functions and tasks.  There are occasions, for example, when I might like to fly but I don't have time and/or patience to spend 20+ minutes getting the engines started.

and

B. How well does the integration work w/r/t the flight engineer tasks.  For example, are you required to switch to FE view mode at critical points when you might otherwise really want/need to be viewing from the pilot's seat?  I find, for example, that simply flying an accurate IFR hold pattern with an A/P is plenty to  handle in a GA twin.

Many thanks again!
