Please note before you read this, I have only had time to quickly write this up. If it is noted on another page, I apologize.
My suggestions are:
Perhaps being able to collect water from natural water sources in clay pots would be a good way of giving Hearthlings a small boost of energy. Could potentially be useful for worker Hearthlings? Plus it gives more of a reason to use the Potter job when not playing in the preferred game world type.
Choosing which farm plot to harvest when it is ready. I have a town of 31 Hearthlings which obviously needs a bit of food. I have also laid out an Oak Tree plot which has fully grown and has been waiting 3 in game days before Hearthlings decide to harvest it.
