I think one thing that is a bit jarring in this game is having to manually toggle to your flare/firework and throw it, then switch back to your weapon. One thing that could alleviate this would be “favoriting” a firework/flare/radio/fuel cell, etc, and then when you use it, you automatically toss one out, complete with contour.
I feel this would add more smoothness to their use and would add a layer of speed to combat.
