You know how in BF1 (and maybe other BF titles too but idk) its vehicles have this indicator showing each player what the vehicle and turret's orientation is? The rectangle stick thing, I don't know how to better describe it. I hope you get the idea.
Edit: turns out the RCB90 already has this, so you definitely know about it. I'm just surprised you haven't done this for all vehicles with turrets yet, please do.
Speaking of the RCB90, I'm not going to make a post for it but it seems like its driver seat actually faces an empty dashboard while Seat 2 (F2) has all the controls and yet whoever sits there cannot drive the boat. Please swap them.
