I would prefer to have it select 1 idle villager at a time as it does in the other 'age of ’ games. I am NOT SURE if this is a bug or if this is the way it is intended but if it IS intended I would like a way to turn it off, because I looked in settings and found nothing to do with how the idle villager banner works, only hotkeys related to selecting idle villagers GROUPS.
I notice that if I control+ Click the idle villager button however it selects one at a time, so anyone else with the problem make sure to control click it to make sure that you select 1 idle villager at a time until more information is known about whether we will be able to toggle this function.
