I see that the provision house has a chimminey but never see any animation to show its working

I'm sure this is the same for some other buildings and i notice the barracks building has animation on all the time .

So we cant tell other then click on it whats its status if it has jobs or not .

So i was just wondering that animation would be a good and easy way to say if building is working, no animation when there are no jobs and not paused.

Thanks
