When editing multiple cards and finalising formatting, it would be great to be able to Copy formatting properties between cards on a Dashboard as opposed to having to individually edit card properties, as each card requires at least 3 clicks to edit attributes; some of our more complex Dashboards have over 100 cards, and this becomes a very laborious task (especially when they are all the same).
An alternative would be a "default" card setting for each Dashboard. e.g. all cards on the Dashboard have a pink background and include the description & timeframe by default.
