First off, loving the game. I've quickly fallen in love with the feel, look, and play. You all are doing an amazing job!
If it's possible, I'd like to suggest servant tasks. My meaning; Servant's (could be Worker classes specific) would be able to pull items from a designated chest and properly refine said item. Example: Servant removes Cotton from chest next to Loom and then places Cotton in Loom to be refined into Cotton Yarn.
I'm sure the coding for this would be "You want what!?" but it's a suggestion.
