pWidget is a new third-party tool for Pivotal Tracker. It’s an embeddable widget, that can be shown in any iframe, and shows stories from multiple projects. Configure it via URL params to show stories matching a search result, from specific projects, in label-specific priority order, and more!
Check out the pWidget page for more details.
