The second suggestion doesn't make much sense.
Sorry for being vague, its just me fancying an old idea about making some items Geoscape consumables through training screen - Pillow Books for freshness recovery, Magical Cakes for stat boost, Regeneration Chambers to cut down on Wounded time, and the like.
And, just to be clear, I`m perfectly fine with current Fatigue mechanics - still, imo, an extra inbuilt "Rest" action might be a good addition to the game. Effectively youll trade all soldier`s TUs for staying Freshness-neutral, and maybe recover about 8 to 10 Stamina. Losing some morale might be a way to compensate, but you lose some to Stress anyway. Although an obvious abuse would be an impenetrable tank Gal drawing fire and providing sight, while staying full on Freshness - but even those are somewhat punished by getting maluses from Bullet Magnet and Gal of Steel.
I guess I can try to make both of those into submods, just to see if its gonna work.
