Smoking, smoke, room heat loss, light, shutters and doors.

[JP_Finn]

Multi-part suggestion INCOMING!

• please enable open/close of shutters (from inside or outside) with same mechanism as doors (i.e. also out of view)
• smoking duration should be decreased to 2-3 days AND would require the fireplace to be burning or hot.
• before entering the smoking room, shutter(s) & door should be opened for "smoke has cleared a bit" similar message to "It smells like *food* is ready". Or get woozy/CO poisoning, when burning fire in sauna/cabin with all shutters closed.
• enable smoke from fires (with a nod to dev note on dry/wet clothes and firewood; wet wood smokes a lot more than dry/cured wood)
• with door/shutters open, expedite heat loss from room&fireplace, moreso with below freezing temperatures. (wake up shivering in your cabin; forgot shutters open and already extremely tired... light small fire with shutters closed... or bigger fire with one shutter open... choices between suffocation & hypothermia 
• enable/disable external light with open/close shutters&doors. (cabins, caves)

This would change the labor&attention, smoking takes, also would make the meat available sooner. If the fireplace--room is cold too long, the meat/fish would spoil, or at best turn out to be awful.
It'd also make winter survival, even with cabin, bit more challenging/intricate; scheduling burning&smoke to clear, prior to going to sleep. Or burn the fire with shutter open and lose some heat.
This'd make using sauna as a smokehouse in winter more inline with historical--present smoking of the delicious animal proteins
