I know we have the history function that has list of updates of the cards.

However, what will be really intersting is to be able to see this visually. So when you click on view history, you pretty much stay in the kanban board, but you can rewind and forward days, and view what the state of the board was on that given day.

I think this is inline with the concept of Kanban that most things visual are better. Visual history is better than CSV files.
