Card history

As request by a message on reddit:

I Would like to add the tracability feature that shows the history of every event the card had gone through

[benjaminapetersen]

This is an interesting feature as well, would definitely be handy. This would be easier to impelment if the "save" action was manual via a user click, but since it is automatic it would be hard to detect and maintain an appropriate historical checkpoint.
