My C-130 wishlist in order of importance:

1. Fix fuel system so that all tanks can be used in any combination without triggering current engine shutdown bug
2. Provide the intermediate position for cargo ramp (and make this ramp position selectable both in the air and on the ground)
3. Add smoke effect for engines
4. Add GPS option (and allow users to slave autopilot to it)
5. Add C-130H-30 variant
6. Allow removal/addition of external fuel tanks
7. Replace clipboard with animations with a a consolidated EFB
8. Continue adding system depth to those items not currently modeled
9. Add L-182 civilian variants (standard and -30 stretch, both with ability to carry external tanks)
10. Add other military external model variants (LC-130H, EC-130H, etc)
11. Upgrade sounds to C-130 sounds
