As customers are working in Superset, any changes that are made across charts, dashboards, datasets, get overwritten so users can't edit confidently. The goal would be to provide some version control functionality so you can go back to a previous version.
One of the biggest pains of using Preset is not having Version Control for charts and dashboards. I wasted so much time reverting manually changes on charts that I unintentionally overwrote instead of creating a new chart. Would love to see it implemented.
