Each Board should have there own card#579

We have feature board inside board great but , the board only show Title , but i need more information,
what if i hav 500 boards inside a board ?

So if we have board inside board : then board will have title only , i need Card also attached with that board : and also a togal arrow button like “V” to show or hide the card , some thig like this screen short

And when i hover over the board (icon 4 square) that i created i need to see the preview off all the card inside that card.

i can do it manually but it too much of work i am trying to write a novel and there is so much to focus if i has card i could just write an idea for a board and workd on other thing , and when i have time i can read it and make it (i don’t remember any of my though and idea ) in board card i could even write task , and much more
