Dual Representation for Boards#98

Boards and cards are two ways to represent “the same information”.

We can either represent info by adding colours, organising in space, addings labels and links to “get the idea” at once; or we can describe it all via text.

I imagine that each board could be represented by a special card. In a way, it is an alternative way to “see the board”.

The default content of the card could be just a list of links to all cards appearing in the board. But each person could be able to change the content of that card.

An example would be: the board is the whole knowledge that goes into a writing piece, and the card contains the written organisation of that piece.
