I want to upvote a card so that I can highlight important ideas
I want to see the total votes of a card so I can identify the most important ones
I want to delete an existing card so I can keep the board clean
I want to be able to revisit my board so that I can review it in the future
I want to edit an existing card so I can correct mistakes
