When using the Clockify/Trello browser extension, the only data that is collected is the Description, Project, and Tags.
The extension should automatically collect some static identifier about the card that is being interacted with…such as the Card ID or Short ID. Trello card names can change over time, but these identifiers (card ID and short ID) remain the same.
Having a static Trello identifier associated with the time entry will enable users to see that potentially multiple time entries originated from the same exact Trello card (even though the Trello card’s name may have changed over time).
