I agree with points 1,3,4,7,8 and 9.
Speaking of the hot bar, I think it would be great to have one slot that you could instantly go to by pressing the hotbar button (instead of holding it to change.) That way you can put a weapon into that slot and be able to quickly change to it. Right now, when an enemy approaches, i sometimes fumble around with the controls in order to find the weapon i want.
