Collapse cards in edit dashboard mode

The dashboard becomes a real mess when you start adding things to it. Especially now with pop-up and such.
What would be nice is to have the cards collapse with an arrow. So that all is small and neat until you really need it. Then you open it. Edit it and collapse it again. You would also need to have the ability to name a card (maybe colorize it) so that it is easyer to find.

So, I am not talking about the dashboard when it is done. I am talking about editing the dashboard.
