From what I have read, DigitalPoint does, or used to have a thread filtering tool in their marketplace under the ebook section that allowed you to filter with options like "Sorted by: number of views...etc." or "sort order: descending or ascending" but I can't seem to find it. I had read that you could find it at the bottom of the page, but it's not there. Does anyone know how to find this or how to filter in such a way? My goal is to find ebooks that have maintained popularity over time, and their "top grossing" or "top rated" filters aren't specific enough an only allow you to filter one at a time.
