When at camp after a battle, you can manage supplies, like tell characters to eat their apples, pills, bandages, etc. This is strategic so you can get them to socialize instead of going to sleep.
However, you need to go to 2 separate menus
-- inspect characters to see their hp / energy, and manage supplies to tell them to eat their vitamins.
1. I suggest making that info (hp / energy / morale / buffs & debuffs, and possibly more) available from the manage supplies menu.
2. I also suggest adding that manage supplies menu available in the morning before you enter the arena, in case you forget to do it at camp. Or when deploying troppa for the arena, in case you forget to do it in the morning.
Thanks!
Way ahead of you! Both of those things are already implemented. ;)
To see morale et al. in the reserve supplies screen, just right-click the character you want to inspect.
To manage reserve supplies during deployment before battle, click the little item sack button.
