Trello Card History Extension

The Trello Card History extension provides quick and easy access to vital historical information for a Trello story card's Description and Name. The change histories for these elements are already stored by Trello, but access to this information is not currently provided by the standard user interface.

This extension is also compatible with the popular Scrum for Trello extension, and will call out Agile point updates as part of its Name change analysis. Teams using Trello for Agile software development can leverage the change history provided by the extension to analyze how well a team is following best practices, such as:

- has a change been made that might invalidate the card's point value?
- are points being assigned/changed as a team?
- are cards following proper grooming procedures before being queued up for development?
- are groomed and/or in-flight cards commonly undergoing substantial revision?
- etc.

Miguel Martinez (ID: 0000007d2f2b0979) Voted 5 ★ - Updated 04/10/2023 It's just great. I just hope trello does not block using this "hidden" feature.

David Quarcoo (ID: 000000cb5f1ef19e) Voted 4 ★ - Updated 07/07/2022 Really great extension for keeping track of changes, my team and I have a big board with a lot of cards so it's a lifesaver for marking down when something was worked on and by who. My only suggestion would be maybe a small notification on the edge of a card to signify that it's been edited? Like I said, we're working with a lot of lists and cards and I think this feature would help pinpoint exactly when something's been changed instead of stumbling upon the change later.
