I am using piwik for creating statistics for a large number of users (few hundreds of them). Each of them has his/her own custom site, with an account to piwik.
This is working fine, thanks to your API, but when I log in with an admin account to piwik, there is just too much information.
It would be nice, if the user list could be separated to pages, or maybe allowing to assign users to groups.
And the same applies for the sites.
So far, that’s all I noticed, otherwise piwik is really nice style_emoticons/<#EMO_DIR#>/smile.gif
Keep up the good work guys!
