My wish would be as you level up your gardening skill you get faster at planting . weeding . watering , harvesting .
Also the ability to tend to more than one patch of garden at once . IE click on a patch to weed and it weeds every patch until they are all done , Or plant and it plants on every patch until you run out of that seed in your inventory , The same with watering , click water and you water every patch that needs it
