To drill down, click the "export" button in the corner. It takes you to the same drill-down screen.
The one piece i miss is the right-click, save image as option. But I installed the "Awesome Screenshot" add-on into Firefox, and that gets me what I need (plus it works in a whole host of OTHER screengrab situations).
IM(ns)HO, the benefits of the new graphs far outweigh the comfort of the old style.
I know how to do it, my point was I miss the previous version. Although even using export you have those annoying mouse overs!
Having to install an add-on to do something you were doing before I think adds to my sentiment.
