Now you might think this is a duplicate but its not. Ive put a lot of thought into this and devs please consider it.
I think that there should be a section on the livery selector where u can click the down arrow and get list liveries for that airline you chose. But not just liveries, also winglets. For example, for southwest airlines you could have all the special southwest liveries on the livery down arrow. Same thing for Jetblue, frontier, etc. For the winglets down arrow on the boeing 737 you may have the option to turn scimitars on and off. Same thing for the airbus A320 sharklets and non sharklets. Some planes may not have these down arrows like the B777 and the A340 but this topic is mainly for the planes that have more than one variant of that plane. This could also apply to the B757 with or without winglets and the same thing for the B767. Pretty much all airlines with different liveries and all planes with different winglets.
This is a picture of what Im talking about. Instead of having Southwest airlines and Southwest(2014) on the livery selector, just put a livery selector on the airline itself instead of making a whole other tab. If this is a little confusing please comment and I will clear things up for you
Also, i was thinking that all the special liveries should cost $0.99, but not the mainline liveries. Like for southwest canyon blue and heart one liveries can be free but liveries like Lone Star one have to be $0.99USD. OR you can make the airline cost more and get all the special liveries. I was thinking instead of paying for the plane itself, u pay for the airline so that you dont have to pay for an airline u never use
