To expand housing to maybe include owning a farm or plot of land to grow Fruit/Vegetable crops that grow over real time? Like a full week, for a harvest of selective crops you planted with seeds and depending on the size of the farm or plot of land you purchased, the amount of crops you are able to harvest. I think this would be a good addition to the game while also requiring an amount of work to be put in by the individual to care for the crops daily. Think of a harvest as a survey for other crafts in amount of materials it can produce.
I checked multiple popular guild traders for certain provisions like potatoes, tomatoes and garlic and barely found any, so another source to obtain them wouldn't go amiss for me.
And while we're on the topic, maybe an option to own a windmill to turn wheat into flour over a weekly process too, for instance 20 wheat for 5 flour. You being of course able to grow your own wheat.
