I have a minor suggestion for the next iteration of the NC HUD: If both of the following conditions are met, lower the position of the reserve-ammo counters to be flush against the slot numbers, so there is no "empty space" in the HUD.
1) The current weapon does not draw from any ammo or stat pool whatsoever.
2) Either there are no inventory items in the game or mod, or there are absolutely no items in the player's inventory whatsoever, therefore hiding the inventory display, since it is not needed.
