First and foremost, thank you for taking the time to read this and please take it seriously.
I suggest that a horse industry be added into the game. The player would create a horse farm (maybe using wheat to feed the horses), then the horse could go to two routes.
It could be made into a horse carriage, by using fir/hardwood and the already existing Wheelmaker. Or it could be used for military purposes, with the horse going to the garrison, or getting horse armor first.
The horse carriages would allow for faster travel of workers to storehouses, and more materials to be carried.
The " War Horse" would allow for faster travel and more health/attack.
Similar to the way that there is a worker in every building that does work, there would be a slot for a carriage as well, and when all workstations are filled with carriages, then the horses would go to the garrison, and when the garrison is full, the horse farm would stop producing horses.
Thank you for reading, I hope you consider it
