Clothing

*Clothing as housing demand (can prevent cold)
*clothing tech tree + production chain
* flax/cotton as new farm productions (unlocked by seeds from exploration?)
* wool from sheep farm
* leather from cattle farm

Can I have an S&M factory where the workers wear only leather?

I really would like to see this one... it was one of the early industries to flourish

and also more meat from cattle and sheep - could be interesting... but do we really need it ? there is so much to go over so far and it will not be a big addition just another 'need' to burden the captain with

I guess you could add silk for high tier clothing, but it would be a pain to make it. Have to find silk worms and white mulberry, it would be a long drawn out production.
Silk would add a lot of unity, or you could trade it for other goods.
