Welcome to the Pivotal Labs community, makers of Pivotal Tracker.
For help, problems and answers to questions https://www.pivotaltracker.com/help is a great place to start. Fellow community members and the Tracker Team will often answer questions here too.
This is a great place for your ideas. There may already be an existing topic that covers your feedback. If you can find one which matches your idea, it is better to "vote" for it and comment rather than opening a new one. Though we can't respond to every idea, we monitor the feedback and popularity here, and do our best to base our product planning and prioritization on it.
