Thanks for a great service. I love Piwik.
You can make it better by adding % in most of the stats.
For example I see an increase in the amount of people who spent 1-10s on the site, however my visitors have increased over time, so it’s normal. % isn’t tricky. If there was a percentage instead, I would probably see a decrease in the % of people who spend 1-10s on the site, which is a goal that I’d like to track accurately.
That’s an example where % would be great. There are other places where it would be appropriate too.
Hope to see this soon
