Oh my friend, thank you so much for these videos of the AN225. I was looking for that kind of videos because my main concern is not the buttons coloration but the seats position of both Captain and Copilot in our actual version. I was hopping they change that in this new update but still really disappointed about that. Fortunately they updated the sound package and I really love it.
I had a long discussion about seats position and even with pictures, videos they are not convinced the yoke is not correctly positioned. Check my discussion here.
On your first video it's clear the yoke is much closer to the dashboard and on the third video looking at the smaller video view where the pilot is seen from the side view, we can see his body is aligned with the smaller side window of the plane. Look in your MSFS model and you'll find the seat position is much backward. They really need to correct that which to me is the most important amelioration to do before the buttons. But I agree, your suggestions would increase the realism.
If they still not convinced about the seat position after looking at your videos, I just don't know what to tell more.
