Nested Boards in Trello

[Bersier]

Wouldn't it be nice if (some) Trello cards could represent boards, which could be accessed by "expanding" the card? Basically, just like folders/directories.

Is there any power-up, or alternative to Trello, that does this?

Note that Trello has already duplicated a significant amount of board functionality within cards through checklists, so that cards can serve as a poor man's board.

@Bersier I do this all the time! Just paste a link to a board onto a card:

Having a "board of boards" is my go to structure for project based businesses.

There's a free Power-Up, Epic Cards by Screenful, that allows specifying some cards to be containers for other cards - across multiple boards. 

This blog post explains how it works:
