We just added a new filter feature, that allows users to filter their lead list (or create a view) that will retrieve any Leads which have an attachment. As you know, you can attach any file to a lead in Open Leads (for example, a PDF document of a contract or sales agreement, a picture of the person with their new car or boat, etc.).
After some feedback from you, our dedicated users, we also tweaked the design a little bit, removing the drop shadow on dialogue boxes. We love to hear from our users, and many of our best new features come directly from your suggestions.
We have several new features in the pipeline to improve your Task Scheduling and Email experience in Open Leads. Check back here for updates or follow us on Twitter or Google+ for the latest news information
