I agree with this ticket, at first I was very happy about the "Enable Vehicle Freelook" option when it was added, but I quickly realized that it's completely pointless if you don't only fly with a joystick. The option should either not apply to air vehicles, or there should be an option to only enable it in ground vehicles. Otherwise, the "Enable Vehicle Freelook" just makes no sense to me.

I'm encountering the same problem when I use
Civilian setFriend [Civilian, 0];

To create Deathmatch missions.

This makes it impossible for the civilians to pick up anything from boxes (they don't show up in the action menu and there is no icon for the box).
Other Parties are unaffected.

Importing the assets from ARMA2 allows you to use Parachutes when ejecting out of airborne vehicles, but I agree that I found it weird that the helicopters in the alpha all do not offer an eject option.

This is identical to the mortars in Arma 2. I guess it's not really an issue, since you're supposed to use the Artillery Computer you can access via the mouse wheel.

I agree with Wallace that some sort of highlighting (ideally highlight all usable ammo for currently equipped weapons) or at least the option to re-enable the autograbbing would be helpful.
In large Weapon Boxes, getting a weapon is rather annoying now, and often I spend a considerable amount of time trying to find the correct ammunition for the weapon I have picked up, and often end up running into action with an unloaded weapon out of Arma 2 habit.

Having the same issue, the entire scene gets darkened to an extend where I can hardly make out anything during the first and last hours of night. During this time it's nearly impossible to read the watch and compass, flashlights, street lights and headlights are weakened and have low range, chemlights hardly provide any light and even muzzle flashes are darkened strongly, opposite of what you would expect in this light condition.

Tried everything, turning Gamma and Brightness all the way up doesn't make it better either.
