Improvements I have on my list:
1. The flap and spoiler levers don't have an animation when they are toggled by a button press which is either commanded from a keyboard or joystick. In my case F8 selects Flaps full position and / key gives full spoilers. In this case these controls move from up position to the end without being slowly transitioned as it is done by on PMDG planes.
2. By default MSFS view in case I want to turn on the VHF2 speaker the flap lever gets highlighted (might be due to being a big click spot).
3. 8X time speed for long routes which should be used without clicking on Auto time compression on the OIS (let it be sim controlled).
4. A little more customized OIS. Having a different background for example. On the load sheet page the number of passengers (first, business, economy) and number of cargo should be given as well instead having just ZFW and fuel quantity.
5. Outside AFT wing view the sound is a bit better since the latest patch but still has a high pitch in my opinion.
