How about, during Auto Follow Player, there's an option to shoot machine gun, or rocket automatically.
(the feature can be toggled; some may not like it)

It's wonderful having an air support like that during scouting where i'm getting overwhelmed by biters, (which basically every single time.)
Then all i have to do is ask the heli to come to back me up
(the arrival would be totally cool to see, just like in the movies !)

Keep the current behavior that the heli will land if the player stand still.
This is for those that just want heli to pick them up and retreat.
Heli only shoot when it's in the air, up until they land.

So, for player that want heli to keep shooting, just keep running around.

Also, just in case user ask for multiple heli escort / auto patrol, given the idea that the heli can now auto attack; I don't think it's necessary.
If you're asking for an army / patrol, there's mod that can do that (AAI).

All i want is the heli to come and rescuing me, and giving itself and me a bit of cover fire.

Bonus request :
Can i have a custom sound when the heli is coming near me ?
(user provided it's own sound, put it manually inside the zip)

I want to hear "Paint it Black" by Rolling Stones, when the heli is coming to me, during shooting. 😁
