this year a lot of WP-Piwik updates were released. Thank you very much for your feedback, which makes it possible to maintain WP-Piwik!
Please consider that I won't be as contactable as usual during holidays. However I'm working on WP-Piwik's next update and I'll try to deliver one more release this year (see the support threads below to get some information about features and fixes I aim for).
Merry Christmas and a Happy New Year!
