With the wave of private servers that are available I thought it would be a good idea for AS to create an Admin panel for them. Right now my understanding is that you have to go through AS support for anything and that can take time, however if you were able to make some small change in house then it might make things more fun.
Ability to add/remove money from airlines
Change airline names
Add aircraft to the market
These are just a few options that would help server owners.
