Ok, can i say that i find really annoying to discover that Piwik doesn’t record when i open outlinks using the middle mouse button (in a new tab), wich i use a lot.
If i use it a lot, maybe many people are using the middle button too. So, we have lost some click stats.
I can understand that it can’t record when people use the contextual menu on a link, but the middle mouse button should have been recorded since Firefox had this function from the start, i think. IE just got tab added. But today most browsers open new tabs on links when we middle click them.
And another thing.
With left clicks, clicking links to my others subdomains from the following blog page show them as outlinks in Piwik.
You can see that for yourself going on that page of my Piwik installation (i gave view permission to anon for somes of my sites).
