dyes - using the current foraging system for things like different color armours, pottery, rugs, beds (bedspreads)
patterns - for use on the loom - the ability to weave from a selection of fabrics and colors (perhaps dying wools or silk - particular interesting for village banners I think)
flowers (also could be used in dye recipes), maybe as an enhancement to beehives (i.e. flowers draw more bees/more production of wax/honey)
clay sculpting (as an offshoot of pottery maybe?) to make sculptures
water fountains (with animations)
Just a couple thoughts from a relatively new player
