Yeah, just like that :) I thought of limiting it to UI-less medkits only (beer will become one in 0.97C, just like combat drugs), since it looks a bit ugly... but boy, so very useful :)
@About healing the enemy: just don't make it a prompt or you will drive me insane, since I do heal enemies rather often, on purpose :) Maybe some modification of the medical UI so it shows WHOM you're healing (a name shown). Otoh beer's going to be UI-less now... :)
