As a colorblind gamer I really wish this would get implemented, or at least a colorblind mode where the indicators are maybe yellow for slightly thirsty, blue for moderately thirsty and then red for really thirsty.

Bandages aren't a necessity anymore. You can just tear up most any shirt into rags and use them. I've found plenty of medical kits which contain gaws (I think) though, and one bandage.
