Farmhand works with Masque to make your buttons pretty. Here I'm using the Diablo III styles for my Farmhand buttons.
Typical view of the farm when using Farmhand.
The seeds bar will show all of the seeds you're carrying. Normally you probably don't have this many seeds or all of the farm tools in your bags. The portal shards icons are optional.
Shows the extra tooltip for seeds in the merchant window with counts of the resulting vegetable in your inventory and the bank.
