1) I love being able to press shift and steady the weapon as the scope is all over the place otherwise. I would just like to see some sort of visual indication of how much longer I have left with the breath hold. There is no physical feedback so a visual feedback would replace that sensation. I can't think of the games off the top of my head but I know I have played FPS games that give this feedback. 2) When I press shift to hold my breath and decide to refocus it's annoying that it "uses up" your entire breath. I think it would make more sense to have a bar that drains over time while shift is being held down and if you don't take the entire breath you can use what is left over when you readjust.
