Hand signals would be awesome - but man it would be so many more keys to map.

G-breathing sound would be cool, is very inmersive.I like in ROF when the view starts to be blured due the wounds, better than only red screen.And what about hipoxia effects? DCS a10 has it very well modeled.Your view starts to bounce and all start to turn black.Finally , you lost controls.
