Stuffed Tracker should provide most of the functionality that you might need out of the box, but we realize its quite possible that you might want something non-standard. That's why we let you modify most of the built-in report parameters or create your own.

Visits length periods, time period templates, custom browser, search engine and page groups -- all of this you can setup in Stuffed Tracker and use in your reports. All your custom parameters will be picked up by the tracker and used in the reports caching and archiving without problems.
