I love farming and I hope, you implement it. Would be nice to combine it with the workshop, like crafting stuff that makes it easier to manage your farming. Love the idea of an irrigation system. In other farming games, you also often have helpers that help you water and harvest crops. The most time-consuming is watering, followed by harvesting and planting.
Maybe you can hire an assisstant that does the work for you? You could have a menu sheet with a simplified overview of your farm area and give that assisstant tasks to do for the day?
But a irrigation system could be enough to cut down routine time.
