For the A320 series with sharklets there should be an option to have them or not.
For example when selecting the aircraft there should be a button to select sharklets or not so that it will be easier than creating a new livery specifically for it. Also the sharklets shouldn’t be added on aircraft liveries or airlines that don’t have them!
There is already a feature request for scimitar option so make sure to vote on that as well!
Thank you, please vote
