- the rate counter is distracting. Also the cynic in me checked the source code (and refreshed a couple of times) and I see it's static. That puts me off slightly. EDIT: I would make it static and just say "Tracking XXXXX events - and counting!"
- the slideshow layout at the top is, I think, broken on Chrome (Linux). For example games, levels, reports seem to appear randomly on the left behind the buttons and some of the slide pages drop over the counter.
Otherwise nice design :)
