When deleting a card, it doesn't specify how many places the card exists. There's workarounds to look at this, but some of those workarounds only work if you have access to the other dashboards / apps to where the card exists. It would be good to give visibility to what the impact would be (even as simple as just a number of places the card exists) to expose to the user that is wanting to delete a card. This could decrease inadvertent impact from happening when deleting a card.
