I'm not going to change the instrument panel texture. Firstly, it can't be seen in any detail:

Secondly it would mean having to regenerate and test 62 new textures for FS9 and again for FSX/P3D. That's a few hours unnecessary work.
The manual explains why I didn't illuminate the slime lights. "Formation keeping “Slime” lights are featured on the real aircraft, but I have not illuminated them on this occasion because they are so small and the resolution would only make them visible at very close quarters". There's a lot of work involved in creating slime lights, It's really not worth the effort in this case. It would also involve 4 new models and a new upload.
The KC-10A manual refers to the C-17's. It says "Replacement files for the East and West Coast packages that remove the old KC-10A’s or KC-135 aircraft that have since been replaced by KC-46A tankers". What is left are the C-17's in the original package.
It's not really possible to extend the cargo door opening times to 10-15 seconds for two reasons. Firstly, the animation would become very jerky and secondly, the aircraft would taxi off the parking spots with the doors still closing, particularly in FSX and P3D.
