Nested / parent boards for cleaner hierarchies

It would be great to have the ability to place boards inside each other, not just in folders. Currently, if I want both a category and a general board for that category, I end up creating two similarly named items.

For example, if I make boards for my favorite foods—“Pizza,” “Hamburger,” “Hot Dog,” etc.—I’d group them in a folder called “Favorite Foods.” But if I also want a general “Favorite Foods” board (a summary or overview), I have to create another board called “Favorite Foods” and put it in the same folder, right alongside the individual food boards. It feels a bit clunky and not quite like a true hierarchy.

Ideally, I’d like to click on “Favorite Foods” itself and either see the ideas directly or open a summary page, without needing both a folder and a separate board.
