first of all: I like Piwik a lot - it’s a great (open source) alternative to Google Analytics. You’re doing a great job (except the empty dashboard after Piwik 1.5 AND 1.5.1-updates, where I couldn’t save any changes…).
Here’s my feature suggestion:
80-90 percent of the collected/saved data about the visitors are unnecessary for me, I don’t need them. Therefore:
It would be great if we could select, which data should be saved/collected from the visitors. This should drastically reduce the size of the database and therefore make Piwik faster (because it’s smaller).
I don’t know what’s the best way to implement such a feature. But if there are boxes, where you can simply select the categories you want to know about your visitors, this would be great.
As I said: Most of the things are not necessary for me. And I asked another user who agreed that he would love to have that feature, too.
I hope you understand what my idea is. Sorry if my English was wrong, I am from Germany
