This is going to be very useful new feature!
If you look at the current rankings screen, you’ll see there is a new column with a graph showing the latest progress for each keyword:
Although there is no new information here, since you could already see this info by going to the historical graph for each keyword (by clicking on the history link), this is an eye opener and very convenient to see all the information at once. Well, at least for me.
Each little graph shows the last 8 or so samples for that keyword. If you want to see more historical information per that keyword, you can click on the history link right next to the keyword (on the left most column), and see the rest of the info.
