Farmhand adds dynamic buttons on the screen while you are at Sunsong Ranch.
The buttons allow quick access to the Plow, Shovel, Bug Spray and Watering Can if they are in your inventory. If you do not have a given item, there will be no button for it. Also adds buttons for seeds that are in your inventory. You can even sell unwanted seeds at a vendor without having to open your bags.
When you leave Halfhill, any tools remaining in your inventory will be dropped. You can pick them up again at the farm. You can disable this using the little lock icon to the left of the tools when you press the SHIFT key.
To move the buttons, hold SHIFT and drag a button with the left mouse button.
I recommend using Masque (optional) to make your buttons pretty.
