Ad a "Done / to do list!"

What about using this free space like that?

The red / yellow / green dots could be used for status purposes: “Green: I am ready … Red: to do…” and a kind of “Master selector” could hide all green cards respectively show all yellow / red cards in order to show the work, that has still to be done…
In my opinion, that will make it much easier to see the current status.
