Minor Update:
This will be a big convenience for visual autopilot adjusters. With this update you dont have to go over the AutoPilot logs and view the reason for increase/decrease of your keyword bid.
In the graph, just click on a particular point (whether the bid was increased or decreased) and a new section below will be populated with the reasons for the bid adjustment. You can go back all the way to six months ago to visualize all the bid changes and the reasons for the bid adjustment.
