Nested Cards Trello Power-up

[Josh Smith]

Does anyone know of a power-up or Chrome extension, etc that will enable me to nest cards to a “parent card" which I can then collapse/un-collapse to view all child cards associated to it?

So ultimately it would be like being able to create multiple Trello lists one on top of the other in different columns, and then create cards under those lists, which you could then unfold and collapse back up to create a more / less detailed vies of all your projects.

So it would be similar to this grid layout (this is “List Layouts" chrome extension) but it would allow you to collapse each of the lists in your columns so that only the List Titles show.

Hi, yes exactly it would just let me collapse the cards under each list title (independently of each list) so that only the title shows. Is there a way to somehow do this? Would I need to get in touch with the contributors on Github?
