First : Thank you for this simulator . I remember, few years ago when FS9/FSX worked difficult on decent computer. Today i can play to AFS2 on a simple macbook pro, graphic quality to maximum.
First question : Can you confirm isn't possible to install add-on on AFS2 ? I have added freeware from ORBX in Library ▸ Containers ▸ com.aerofly.aerofly-fs-2-mac ▸ Data ▸ Library ▸ Application Support ▸ Aerofly FS 2 ▸ addons ▸ scenery but the scenery dont show in AFS2.
Second question : Do you plan to share the A320 paintkit ? I think A320 is one of most famous airplane in "actually world" and possibility are huge to repaint it. I can contribute ;).
Suggestion : touchdown smoke when hard landing
