Right now, the dashboard is fairly complicated. If someone just wanted to know "how many people use my add-on on Windows?", there's not a super easy way to figure that out. The graphs are more of an "advanced" option. I'm trying to think of ways to make it easer for an average user who just wants to know the basics. One idea is making the summary table tabbed and having totals on the tabs for the various add-on versions and operating systems.
