I find that at night, you can barely see the taxiway, even if my phone is on full brightness. A way to fix this would to add taxiway lighting so this would never happen. I think I am not the only one with this problem. The light would also make the airports look way better at night, this could definitely be a factor why someone would choose IF instead of Aerofly.
Another thing is Clouds, it can be very dull flying sometimes, and adding clouds would make it way more interesting to fly, so it is not just a dull flight.
A small thing I would also like to see is tire smoke, its a small thing but it would be very nice.
The things listed have a way higher priority to me, than always adding new aircraft, since the devs have made so many great aircraft. There are so many to choose from, and I find adding these features are more important than other things.
I hope someone sees this, and passes it on to the devs,
Thanks.
