Here's how it cuts down on the time. Before, you had to use the mouse to click on the building, then move the mouse to the proper production slot and click it, then move the mouse back to the next building. Very time consuming. Now, you ony use the mouse to select the building. Then, with your other hand parked over the appropriate number key (6 for 24 hour cycle), you press that key. Move the mouse to the next building, press key. Your off hand never has to move except to press the key. Your mouse only moves once per building, not twice. It is lightning quick. I am absolutely sure that when
@sloppyjoeslayer gets used to it, his time will be cut down to well under 4 minutes. I do a little quest looping on all 4 of my active worlds, and it is amazing now how quickly it goes when resetting the buildings.
