Adds a villager stats counter to the default user interface. The number of villagers gathering each resource will be shown next to the resource counters. Multiplayer compatible.
They added this in because of modders? Well, it's nice to see they learn from the community and improve the game because of it. It's a good mod. I was a little surprised when I started playing that this was in there, since I hadn't played in years before buying the game on Steam to try out the new content, but it's pretty handy to know how much influx of gold, food, wood and favor you have.
It wasn't included when the game was first released - they added it because mods like this we so popular.
