Feature Idea: View cards in hidden column

[Johennes]

Summary:

I can drag cards from a visible into a hidden column by dropping them on the column name in the "Hidden columns" group. It would be nice if the inverse operation, moving a card from a hidden column into a visible one, was also supported.

The number of cards in a hidden column already highlights on hovering but clicking it has no effect. Maybe clicking the number could show the cards in the column in a pop-up and allow dragging them into a visible column.

How important this is to me and why:

Importance: Low

Low importance since for my main use case CTRL/CMD-Z also works, but is less discoverable.

Use cases:

1. I moved a card into a hidden column by accident and want to move it back
