Pivotal Extensions is a free Chrome add-on developed by Patrick Elam that aims to enhance the usability of Pivotal Tracker, a popular project management tool. This add-on makes several tweaks to Pivotal Tracker's user interface, providing teams with important information at a glance.

One of the key features of Pivotal Extensions is the "Days in Progress" functionality. This feature adds a sun emoji for each day a story has been in progress. By visually representing the number of days a story has been active, it helps bring attention to long-running stories that may have been overlooked. This is particularly useful for teams that have stories that are expected to be completed within a certain timeframe.

Another useful feature offered by Pivotal Extensions is the "Iteration Progress" indicator. This feature adds a series of progress bars above the current iteration column header, giving a visual indication of how far the team is in completing the stories and points for the current iteration. This allows teams to easily track their progress and ensures that they stay on track to meet their goals.

Overall, Pivotal Extensions is a valuable add-on for Pivotal Tracker users who want to enhance the usability of the tool and improve their project management experience. With its intuitive tweaks to the user interface, it provides teams with important information at a glance, helping them stay organized and efficient.
