Back when I had my old monitor, I always had issues accidentally clicking on HUD when the target was on the lower edges of screen, which was rather annoying cause I don't like playing with collapsed HUD, but since I got my new widescreen monitor, I've never had that issue again because there's always some room to aim at the edges of the screen.
So if it's ever gonna be implemented on Disco installation, I believe it'd be better if it's put in as an option the player can enable on mod activation, rather than a default feature.
