I had that same question. There is a console command that allows for unlimited energy, but setting sv_cheats to 1 disables a number of game elements. Might it be possible to see how the game writes to stamina while that's enabled? I wonder if then you might be able to replicate the process to make an unlimited stamina option without the cheat flag active.

I would also like to ask if in a future release if the value for unlimited health could be set higher. It's just a quirk of mine really, but I figured if another version gets released it wouldn't be too hard to do. I noticed the option sets health at 159. If your maximum health goes above that then there's this steadily increasing black section on your health bar as you level further. (And it does happen. Presumably you must take the same character through the campaign four times for the "real" ending.) Again, not a problem per se, just a thing I can't help but notice out of the corner of my eye, lol.

In relation to the health option, though, I did also notice a small bug. Once the option has been activated you can no longer heal yourself in that level. If it's deactivated when you change levels (Temple HQ to side mission or campaign mission anc vice versa) then healing will work normally. I discovered that when I decided to try running without it for a while and could not restore my health no matter how high the number on my medkit was. I can always just turn on the option again, so I'd definitely call it minor, but it might be worth looking at it.
