Currently you can rotate the view around but it stops at about 150 degrees or so. I want to be able to rotate to the full 180 degrees. So I do an attack run in my chopper and then as I fly away, I can rotate the view and see directly behind me.
I know you can do this with the DEL key to engage tactical mode or whatever, but it really should be part of the normal view rotate key. I have wanted this for years.
