I really liked being able to view total visitors and unique visitors as separate graphs, and would not have installed the update if I had known I would lose that feature.
I was also dismayed by the loss of the download feature, and find the thick lines on the new graph unattractive and hard to read.
Is there a way to roll back the update? If not, I'll probably change to a different plugin. Updates are supposed to add or improve features, not reduce them.
