Since probably no one is running piwik longer than one year, this is not important at the moment. But for later it would make sense to have on overview off all your data at once. Therefore, create an 'all'-tab next to 'day', 'month' and 'year'.
i think this actually IS important at thr moment as I believe that if you choose "year" only data of the currently running year will be shown. Result: if it's jan 01 2009 you will not see 2008's data any more unless you choose dec 31 2008 or anything similar...
after piwik 1.0? It will take another year or so until we can see this feature? is it really that hard to implement?
That milestone is a catch-all for feature requests. We regularly review the outstanding tickets in the system and adjust the roadmap.
p.s. code contributions are welcome.
