This mod adds a new feature to the flashlight that I find very interesting: it only turns on when you're aiming with it. However, I suggest replacing this with an on/off interface, either with a single keystroke, or toggling it with a left-click.
This suggestion is also motivated because I've noticed that once you put the flashlight on your head, there's no way to get it to work and illuminate.
Although if there is something I am doing wrong, I would appreciate it if someone could tell me how I can do it, and I have already tried everything I can think of.
