Overall, I really like the UI and see lots of value in the tool. A few areas of bugginess / improvements I would recommend:
Preparation - Add fields: typing in the search freezes the window, reported by multiple users
Analysis - Not useful until can be published to Report Builder / external stakeholders
Configure - Why is end date a required field, prefer to have this run until stopped. Can this refresh more frequently, CSMs prefer to see real-time or near real-time data.
